What is Cement? – Cement is a binding material that hardens when mixed with water. When cement is added to solid particles like sand, aggregate or stones and mixed with water, it binds them together into a compact durable mass. If the early history of cement is to be considered, the ancient civilizations such as Romans, Egyptians and Indians were known to have used cementing materials in their ancient constructions.
Who invented Portland cement?
The Invention of Portland Cement – The modern cement we commonly use is Portland cement. The invention of Portland cement is attributed to Joseph Aspdin, who was a leed builder and bricklayer. The patent of Portland cement was registered on 21st October 1824 by Joseph Aspdin.
- As the appearance of the cement after hardening was very similar to natural stones found at Portland in England, it was named Portland cement.
- In the process invented by Aspdin, hard limestones war ground and mixed with finely divided clay in form of slurry.
- Then this salary was calcined in the furnace similar to a line kiln till carbon dioxide was formed and expelled from it.
After this calcined mixture was ground into a very fine powder which was called Portland cement. In his process, Aspdin might have used a temperature lower than clinkering temperature. Later in 1845, Isaac Charles Johnson burnt this mixture of clay and limestone till clinkering stage to produce better cement.
Isaac Charles Johnson established factories in 1851 to produce this version of Portland cement. As later the use of Portland cement increased, higher quality and standard of material was needed for Major construction works. This led to the establishment of an association of engineers, consumers, and cement manufacturers to specify the standards of cement.
Definition: Cement is a binding material that when mixed with water and solid particles such as sand, aggregate, or stones, binds together into a compact durable mass. The invention of Portland cement is generally accredited to Joseph Aspdin, who was a leed builder and bricklayer.

Joseph Aspdin first developed cement in 1824.
Who invented the first concrete structure?
The first concrete-like structures were built by the Nabataea traders or Bedouins who occupied and controlled a series of oases and developed a small empire in the regions of southern Syria and northern Jordan around 6500 BC. This knowledge was continually improved by people in the area, with a multitude of iterations as centuries passed.
What is concrete made from?
History – Plaque in Leeds commemorating Joseph Aspdin Portland cement was developed from natural cements made in Britain beginning in the middle of the 18th century. Its name is derived from its similarity to Portland stone, a type of building stone quarried on the Isle of Portland in Dorset, England. The development of modern portland cement (sometimes called ordinary or normal portland cement) began in 1756, when John Smeaton experimented with combinations of different limestones and additives, including trass and pozzolanas, intended for the construction of a lighthouse, now known as Smeaton’s Tower,
In the late 18th century, Roman cement was developed and patented in 1796 by James Parker, Roman cement quickly became popular, but was largely replaced by portland cement in the 1850s. In 1811, James Frost produced a cement he called British cement. James Frost is reported to have erected a manufactory for making of an artificial cement in 1826.
In 1811 Edgar Dobbs of Southwark patented a cement of the kind invented 7 years later by the French engineer Louis Vicat, Vicat’s cement is an artificial hydraulic lime, and is considered the “principal forerunner” of portland cement. The name portland cement is recorded in a directory published in 1823 being associated with a William Lockwood and possibly others.
- In his 1824 cement patent, Joseph Aspdin called his invention “portland cement” because of its resemblance to Portland stone,
- Aspdin’s cement was nothing like modern portland cement, but a first step in the development of modern portland cement, and has been called a “proto-portland cement”.
- William Aspdin had left his father’s company, to form his own cement manufactury.
In the 1840s William Aspdin, apparently accidentally, produced calcium silicates which are a middle step in the development of portland cement. In 1848, William Aspdin further improved his cement. Then, in 1853, he moved to Germany, where he was involved in cement making.
- William Aspdin made what could be called “meso-portland cement” (a mix of portland cement and hydraulic lime).
- Isaac Charles Johnson further refined the production of “meso-portland cement” (middle stage of development), and claimed to be the real father of portland cement.
- In 1859, John Grant of the Metropolitan Board of Works, set out requirements for cement to be used in the London sewer project,
This became a specification for portland cement. The next development in the manufacture of portland cement was the introduction of the rotary kiln, patented by Frederick Ransome in 1885 (U.K.) and 1886 (U.S.); which allowed a stronger, more homogeneous mixture and a continuous manufacturing process.
The Hoffmann “endless” kiln which was said to give “perfect control over combustion” was tested in 1860 and shown to produce a superior grade of cement. This cement was made at the Portland Cementfabrik Stern at Stettin, which was the first to use a Hoffmann kiln. The Association of German Cement Manufacturers issued a standard on portland cement in 1878.
Portland cement had been imported into the United States from Germany and England, and in the 1870s and 1880s, it was being produced by Eagle Portland cement near Kalamazoo, Michigan. In 1875, the first portland cement was produced in the Coplay Cement Company Kilns under the direction of David O.
When was the first concrete made?
The Age of Enlightenment – In 1756, the British engineer John Smeaton made the first modern concrete (hydraulic cement) by adding pebbles as a coarse aggregate and mixing powered brick into the cement. Smeaton developed his new formula for concrete in order to build the third Eddystone Lighthouse, but his innovation drove a huge surge in the use of concrete in modern structures.
What is the history of Portland cement?
The word “cement” is derived from the Latin word “caementum”, which means chipped rock fragments. Limestone is well known to be the oldest material to be used as a binder. Lime was produced by heating near pure limestone, and lime mortar was created by adding and mixing water and sand. The ancient Greeks mixed volcanic tuff from the island of Santorini with lime to obtain mortar, or used a clayey limestone to produce a kind of hydraulic lime that was used for the production of mortar. In Egypt, impure calcinated gypsum was used rather than cement.
- Almost 2000 years ago, the Greeks and Romans ground lime and “pozzolin” – a volcanic ash that is these days known as “pozzolana” – and used the mixture as mortar in masonry with the addition of sand.
- Although various binders were used in ancient times, studies of ancient construction methods have been unable to garner much information on how these binders were obtained, or the working conditions.
For example, Roman philosopher Gaius Plinius wrote, “. it is beyond understanding how lime burns when it comes in contact with water, after having previously been obtained by burning with fire”. The use of cement in Roman architecture started with the Colosseum and the Roman Baths in 27 BC. A sample of Roman Architecture. In England, volcanic ash was ground and used in the manufacture of bricks and roof tiles. Large Medieval cathedrals such as those of Chartres and Rheims in France, and those in Durham, Lincoln and Rochester in England, were constructed using what were advanced technologies at the time.
The Romans were unaware of the technologies being used 1,000 years earlier. Most probably, the Romans identified the characteristic features of volcanic ash, and used it in their buildings for various purposes. Marcus Vitruvius Pollio, a Roman architect and engineer who lived in 1 AD, detailed structures and related technologies from the past in his book “Ten Books of Architecture”, and recommended concrete for its ability to give “polish to the floor and to create a strong foundation”.
The book also mentioned the use of mixed lime and crushed rock, pozzolan, for the reinforcement of buildings, which is also said to preserve its hardness underwater. European societies lagged behind the Romans. Mortars were prepared especially using lime, and setting took a reasonably long period of time. Aqueduct, Segovia – Spain In 1756, John Smeaton, who was given the responsibility for the construction of Eddystone Lighthouse, studied the chemical features of lime, and reached significant conclusions on its binding qualities. Later, in the light of these studies, Joseph Parker produced a binder known as “Roman Cement”, for which raw material was obtained from the limestone around London, and the produced binder was used in the construction of canals and ports.
The “English Cement” produced by James Frost in the same era was not as popular as Roman Cement. The Renaissance ushered in a new era in which people were encouraged to think in different ways, and the doors of the industrial revolution were thrown wide-opened. The naval fleet of England, comprising ships for trade and exploitation, required new lighthouses in the 18th century, and this became a driving force for the cement industries.
Eddystone Cliff near the Port of Plymouth in England had long posed a threat to the constant flow of vessels entering and exiting the port. Using mortars that hardened underwater, with a view to providing convenience to sailors, the construction of the 37-m high Eddystone Lighthouse was completed between 1757 and 1759, built from a mixture of lime, water, clay and iron cinder.
- The lighthouse was fixed to iron rods embedded in holes in the sea floor and secured with lead.
- In 1756, English engineer John Smeaton determined that the best cement was based on soft limestone with a certain amount of clay content.
- Almost 40 years later, James Parker produced cement in England using limestone with a high impurity ratio.
The production of cement out of clay and limestone was initiated in France in 1813 by Louis Vicat, and in England in 1822 by James Frost. The binder produced by Louis Vicat went on to be used in bridges and concrete canals. Vicat studied the feature of under-water setting of the hydraulic cement, the binders that were obtained by mixing the lime and the pozzolan, and the natural cement.
He produced a synthetic binder by mixing silica, aluminum and lime at certain amounts. His studies, experiments shed a light on production of Portland Cement that is widely used today. Vicat used his hydraulic binder in one of the abutments of the Souillac Bridge, the construction of which was completed in 1822.
In 1824, Joseph Aspdin, a mason from Leeds, heated ground clay and limestone until the limestone calcified, and then ground the mixture once again, observing that the mixture set some time later after adding water. Aspdin named his creation “Portland Cement”, due to its resemblance to the rock extracted from quarries on the “Isle of Portland on the British Coast”, and its use became widespread in the construction of buildings in England. Joseph Aspdin, 1824 The “Wakefield Arms” building, which is still standing next to Kirkgate Station in England, is known to have been constructed using the binder produced by Joseph Aspdin. A process involving the baking of raw materials at high temperatures was devised by Isaac Johnson in 1845.
- In 1845, Isaac Johnson baked a mixture of lime and clay mixture at a temperature of 1400°–1500°C – as is still done today – to produce the first modern Portland Cement.
- Thus, the significance of heat in the production of cement was recognized.
- At high temperatures, clinkerization occurs, and more reactive and strong cement components are created.
The first half of the 19th century saw a considerable increase in demand for cement in America. In 1818, one year after the excavation for the Erie Canal was begun, engineer Canvass White found that the material being extracted from a quarry in Madison County developed natural hydraulic characteristics after undergoing a simple process.
- Cement produced using this material was used in the construction of Erie Canal.
- In 1850, David O.
- Saylor, an American, produced natural cement after baking and grinding a cement rock he had identified, although it was determined that the strength of the natural cement produced in the United States and some other countries was lower than that of Portland Cement.
Although the production of cement increased by1850, it was not produced in the United States in any great quantities until the 1870s. The first export of cement from Europe to the United States was made in 1868, and by 1885, exports had reached 3 million barrels.
The first cement factory in the United States was opened in 1871 by David O. Saylor. Saylor produced John K. Shinnportland cement in Philadelphia in 1876, making use of different materials extracted from his own quarries. Formations suitable for cement production were subsequently identified in Rosendale, New York, and in Indiana, Kentucky and Lehigh Valley, Pennsylvania.
In 1874, Robert W. Lesley claimed that workmanship costs would drop if the material was fed to the furnaces in chunks. In 1880, 42 million barrels of cement were produced in the United States, and cement production reached 335 million barrels in the decade that followed.
The most significant factor driving the increase in production was the developments seen in rotary furnaces. Earlier vertical furnaces had to be filled and emptied after each production phase, but were replaced by rotary furnaces, which enabled continuous production. The rotary furnaces came to replace the original vertical shaft furnaces that were used for the production of lime in the 1890s.
In rotary furnaces, heat transfer and heat treatment were achieved under better conditions, and so higher temperature values were attained. In 1885, Frederick Ransome, an English engineer, obtained a patent for a less inclined rotary furnace. In inclined rotary furnaces, as the material in the furnace moves toward the outlet due to the motion of the furnace, production capacity is increased and more homogenous products are obtained.
- Vertical furnaces were subsequently replaced by new inclined rotary furnaces.
- At the end of the 19th century, plaster stone was added to the clinker, and ball mills were used for grinding.
- In 1902 Thomas A.
- Edison installed the longest furnace (45 m) built to date in the New Jersey Portland Cement Works.
Together with the usage of longer furnaces, and taking advantage of the developments in crushing and grinding mills, the capacities of cement facilities have been increased. The first broad engineering application of Portland Cement was seen in the tunnel bored under the River Thames in 1928, for which a facility was opened in Wakefield for the production of cement.
In short, the name “Portland” comes from a construction rock sourced from Portland, and that has similar qualities to Portland cement (Taylor, 1992). Although the date Portland cement was invented is not known, its patent was obtained by J. Aspdin in 1824. Although the optimum heat treatment applied in the production of Portland Cement produced today ensure superior features to the cement produced by J.
Aspdin, he should be recognized in literature as the person who invented cement. In 1845, Isaac Johnson used the same raw materials in his cement as the Portland Cement used today. In England in 1825, James Frost initiated constant production of Portland Cement in Swanscombe, while the first cement factories to be constructed in Belgium and Germany opened in 1855.
- The first studies of cement in the United States began in 1865, and Portland Cement production was launched in 1871.
- Regular investigations into the composition of Portland cement were launched, and in 1906 heat treatment and production methods were applied based on scientific foundations.
- The first cement trucks were used in Baltimore, Maryland in 1913.
Since 1926, many scientific studies have been conducted into Portland Cement in various countries, and the development of hydraulic cement has been maintained. In the 1900s, the use of rotary furnaces for heat treatment; the use of ball mills for grinding the raw materials and clinker; and the addition of plaster stone and the other additives to clinker led to improvements in cement quality, and significant developments have been witnessed in production processes over time.
Lepol system by Polysius in 1928, Vertical roll furnace in 1930, Pre-furnace pre-heating cyclones in 1932, Fuller grill cooler in 1937 Mechanical classifiers in 1950, The first furnace side-passing system in 1960, The pre-calcification system in 1966, High-productive classifiers in 1970, Calcination systems using tertiary air coming from the cooler in 1973.
In the years to come, new arrangements aimed at reducing costs will be applied, especially those that make use of all the heat produced in the system.
Who invented re-reinforced concrete?
The Industrial Revolution – Concrete took a historic step forward with the inclusion of embedded metal (usually steel) to form what’s now called reinforced concrete or ferroconcrete. Reinforced concrete was invented in 1849 by Joseph Monier, who received a patent in 1867.
- Monier was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh.
- Reinforced concrete combines the tensile or bendable strength of metal and the compressional strength of concrete to withstand heavy loads.
- Monier exhibited his invention at the Paris Exposition of 1867.
Besides his pots and tubs, Monier promoted reinforced concrete for use in railway ties, pipes, floors, and arches. Its uses also ended up including the first concrete-reinforced bridge and massive structures such as the Hoover and Grand Coulee dams.
What are the technological milestones in the history of concrete?
The Historical Evolution of Concrete – There is no denying that concrete and the technology surrounding it has come a long way since its discovery and development. From the Great Pyramids at Giza to smart sensors for testing concrete temperature, maturity, etc., we’ve put together a list of notable events and discoveries in the history of concrete.
Request a Virtual Demo of our SmartRock Wireless Sensor 6500BC – UAE: The earliest recordings of concrete structures date back to 6500BC by the Nabataea traders in regions of Syria and Jordan. They created concrete floors, housing structures, and underground cisterns.3000 BC – Egypt and China: Egyptians used mud mixed with straw to bind dried bricks.
The history of concrete
They also used gypsum mortars and mortars of lime in the pyramids. The Great Pyramids at Giza used about 500,000 tons of mortar. A form of cement was also used to build the Great Wall of China around this time.600 BC – Rome: Although the Ancient Romans weren’t the first to create concrete, they were first to utilize this material widespread.
- By 200 BC, the Romans successfully implemented the use of concrete in the majority of their construction.
- They used a mixture of volcanic ash, lime, and seawater to form the mix.
- They then packed the mix into wooden forms, and once hardened, stacked the blocks like brick.
- After more than 2,000 years, Roman concrete structures stand tall due to their ingredients colliding with Earth’s natural chemistry.
Technological Milestones: during the Middle Ages, concrete technology crept backward. After the fall of the Roman Empire in 476 AD, the technique for making pozzolan cement was lost until the discovery of manuscripts describing it was found in 1414. This rekindled interest in building with concrete.
It wasn’t until 1793 that the technology took a big leap forward when John Smeaton discovered a more modern method for producing hydraulic lime for cement. He used limestone containing clay that was fired until it turned into clinker, which was then ground into powder. He used this material in the historic rebuilding of the Eddystone Lighthouse in Cornwall, England.
In 1824 Joseph Aspdin invented Portland cement by burning finely ground chalk and clay until the carbon dioxide was removed. Aspdin named the cement after the high-quality building stones quarried in Portland, England. In the 19th Century concrete was used mainly for industrial buildings.
