English bond Flemish bond Stretcher bond Header bond
It is the arrangement of bonding that consists of alternate courses of stretcher and header placed one over other, In order to break the alignment of vertical joints to be in the same straight line queen closer is placed next to the quoin header in each alternate course. Header courses must not start from queen closer as it is liable to get displace off. A lap of one-fourth brick is available for each stretcher over the header in the course below it. For the wall having the thickness in the odd multiples of half brick thick, each course shows a stretcher on one face and a header on the other face.
It is the arrangement of bonding that consists of an alternate header and stretcher in each course, The header in each alternate course is centered over the stretcher in the course below it. In order to break the alignment of the vertical joint to be in the same straight line queen closer is placed next to the quoin header. For walls having a thickness greater than 1.5 brick thick, an English bond is found to be stronger than a Flemish bond, however, a Flemish bond renders a higher aesthetic appearance than an English bond, Flemish bond is more economical than the English bond.
It is the arrangement of bonding that consists of a stretcher in each course, In order to break the alignment of the vertical joint to be in the same straight line each alternate course started with the half-bat. A lap of half-brick is available for each stretcher in all the courses. This bond is provided when a half brick thick wall is required.
It is the arrangement of bonding that consists of a header in each course, In order to break the alignment of the vertical joint to be in the same straight line each alternate course started in the quarter bat.

English bonds used in bricks is: _. Free 10 Questions 10 Marks 7 Mins Explanation: Important types of bond in brick masonry:
All the bricks are laid as stretchers or full brick which is laid with its length parallel to face the wall. Used-in half brick thick walls.
All the bricks are laid as headers or full brick which is laid with its width parallel to face the wall. The elevation of the wall laid in Header bond. Used for curved surfaces in work such as well lining or well foundation etc.
Alternate courses of headers and stretchers, Most common and popular bond. One of the strongest bonds but requires more facing bricks than other bonds. It is costly as compared to other bond.
Each course consists of a header and structures alternately arranged. Uses a greater number of brickbats and hence it is economical, It is of two types: Single Flemish and Double Flemish. Better in appearance than the English bond.
This bond is used where the bricks of specific thickness are to be used in the facing and backing of the wall. A header course is provided after several stretcher courses.

Which is the most popular type of brick masonry?
1. Burnt Clay Bricks – Burnt clay bricks are also known as common bricks because they are the most abundant brick type in modern construction. These bricks are used in columns, walls, foundations, and more with a wide variety of purposes. When building walls, the burnt clay bricks require plastering or rendering with mortar to help improve the bricks’ strength, water resistance, and insulating ability.
These bricks are split into four different class categories based on quality. Fourth-class bricks are over-burnt, irregular in shape, and commonly broken down for use as an aggregate. Third-class bricks are poor-quality materials that should only be used for temporary structures. Second-class bricks are of moderate quality, though they have an irregular shape, rough surface, and might have hair-thin cracks.
First-class bricks are the best of the burnt clay brick classifications. These high-quality bricks have a standard shape, smooth surface, and increased durability and strength. Best For: Made for a variety of purposes, burnt clay bricks are the most versatile brick used in modern construction.
Which brick is best for house construction?
Sand Lime Bricks – Sand lime bricks are a mix of sand and lime. These bricks have a smooth and uniform finish and are fire-resistant. They have a grey colour, unlike reddish burnt clay bricks. Sand lime bricks are strong and sturdy bricks with high compressive strength. They are the best bricks for load-bearing wall construction in homes and for multi-storied buildings. Sand lime bricks don’t need a high amount of mortar plaster, which reduces the cost of a construction project. These dense bricks don’t pass sound easily, so it provides good acoustic insulation.
What are two types of brick bonds?
These are: Running bond, common or American bond, Flemish bond, English bond and block or stack bond, as illustrated in Fig.3.

Why is the euro bond attractive?
How Do Eurobonds Work? – The essence of Eurobonds is that a company can choose any country to issue bonds depending on its economic and regulatory environment (e.g., interest rates in the country, economic cycle, market sizes, etc.). What makes the bonds attractive among investors is a small notional amount of a bond (face value or par value ), which means that the bond is relatively cheap to obtain.
How is a euro bond priced?
Fixed-rate bonds in euros are priced using the so-called mid-swaps annual vs six-month Euribor curve. While bonds are priced using the swap curve, they are usually traded using the German Government bond curve as the benchmark.
Why is bond so expensive?
Pricing Moves – Bonds are issued with a set face value and trade at par when the current price is equal to the face value. Bonds trade at a premium when the current price is higher than the face value. For example, a $1,000 face value bond selling at $1,200 is trading at a premium.
Discount bonds are the opposite, selling for lower than the listed face value. Since the interest paid on bonds is fixed, bonds that are priced lower have higher yields. They are more attractive to investors, all other things being equal. For instance, a $1,000 face value bond with a 6% interest rate pays $60 in annual interest every year regardless of the current trading price.
Interest payments are fixed. When the bond is currently trading at $800, that $60 interest payment creates a present yield of 7.5%. Supply and demand can influence the prices of all assets, including bonds. Bonds with higher yields and lower prices usually have lower prices for a reason.

When would you use a Flemish bond?
english bond – stretcher bond Garden walls built using Flemish bond are one bricks wide. As with any wall built of brick, no two adjacent vertical joints should be in line. With a straight wall this is not a problem, just offset each course so that the header bricks are centred on the stretcher bricks on the course below. Use Flemish bond for a half brick width wall can give a decorative finish but does require the use of quite a few half bats (coloured green) and three quarter bats (coloured red). Bricks and Bats
