What is the ratio of one cement and sand?

A general teacher’s guide for concrete preparation – The physical properties of density and strength of concrete are determined, in part, by the proportions of the three key ingredients, water, cement, and aggregate. You have your choice of proportioning ingredients by volume or by weight.

Proportioning by volume is less accurate, however due to the time constraints of a class time period this may be the preferred method. A basic mixture of mortar can be made using the volume proportions of 1 water : 2 cement : 3 sand. Most of the student activities can be conducted using this basic mixture.

Another “old rule of thumb” for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability.

The mix should not be too stiff or too sloppy. It is difficult to form good test specimens if it is too stiff. If it is too sloppy, water may separate (bleed) from the mixture. Remember that water is the key ingredient. Too much water results in weak concrete. Too little water results in a concrete that is unworkable.

Suggestions:

  1. If predetermined quantities are used, the method used to make concrete is to dry blend solids and then slowly add water (with admixtures, if used).
  2. It is usual to dissolve admixtures in the mix water before adding it to the concrete. Superplasticizer is an exception.
  3. Forms can be made from many materials. Cylindrical forms can be plastic or paper tubes, pipe insulation, cups, etc. The concrete needs to be easily removed from the forms. Pipe insulation from a hardware store was used for lab trials. This foam-like material was easy to work with and is reusable with the addition of tape. The bottom of the forms can be taped, corked, set on glass plates, etc. Small plastic weighing trays or Dairy Queen banana split dishes can be used as forms for boats or canoes.
  4. If compression tests are done, it may be of interest to spread universal indicator over the broken face and note any color changes from inside to outside. You may see a yellowish surface due to carbonation from CO 2 in the atmosphere. The inside may be blue due to calcium hydroxide.
  5. To answer the proverbial question, “Is this right?” a slump test may be performed. A slump test involves filling an inverted, bottomless cone with the concrete mixture. A Styrofoam or paper cup with the bottom removed makes a good bottomless cone. Make sure to pack the concrete several times while filling the cone. Carefully remove the cone by lifting it straight upward. Place the cone beside the pile of concrete. The pile should be about 1/2 to 3/4 the height of the cone for a concrete mixture with good workability. (SEE DIAGRAM)
  6. To strengthen samples and to promote hydration, soak concrete in water (after it is set).
  7. Wet sand may carry considerable water, so the amount of mix water should be reduced to compensate.
  8. Air bubbles in the molds will become weak points during strength tests. They can be eliminated by:
    • i. packing the concrete.
    • ii. Tapping the sides of the mold while filling the mold.
    • iii. “rodding” the concrete inside the mold with a thin spatula.
  9. Special chemicals called “water reducing agents” are used to improve workability at low water to cement ratios and thus produce higher strengths. Most ready-mix companies use these chemicals, which are known commercially as superplasticizers. They will probably be willing to give you some at no charge.
  10. You can buy a bag of cement from your local hardware store. A bag contains 94 lb. (40kg) of cement. Once the bag has been opened, place it inside a garbage bag (or two) that is well sealed from air. This will keep the cement fresh during the semester. An open bag will pick up moisture and the resulting concrete may be weaker. Once cement develops lumps, it must be discarded. The ready mix company in your area may give you cement free of charge in a plastic pail.

What is the plaster ratio?

How do I mix plaster? The easiest way to mix plaster is to place the water in a bucket and sift the plaster through fingers until it forms a mountain in the water with a “peak” rising above the water. Allow the plaster to sink. You should see a noticeable increase in the length of time the plaster floats on the surface before sinking as additions continue.

When all the plaster is added and submerged, mix slowly but thoroughly, breaking up all chunks and try not to introduce air into the mix. Use your hand or a power mixer on a low setting, Continue mixing until the plaster thickens slightly or until a finger drawn across the surface leaves a trace trail, then pour slowly into your form.

Tap or lightly shake the form to bring air bubbles to the surface. Let set, remove from form and dry completely before using. How much water do I add? The water/plaster ratio is referred to as consistency. It is expressed as parts water per 100 parts plaster.

  • Typical consistencies for Pottery Plaster (K60) range from 60-75 (60-75/100).
  • Slip casting molds water/plaster ratio of 1 lb.
  • 1-1/2 lbs.
  • Press molds, wedging surfaces and bats water/plaster ratio 1 : 1-3/8 lbs.
  • Typical consistencies for DensitePlaster (K5) range from 34-35 (34-35/100).
  • Which plaster should I use? Pottery Plaster (K60) is primarily used for slip casting molds, press molds, wedging tables & bats.

Developed as an intermediate grade plaster that provides improved absorption and longer mold life. Densite Plaster (K-5) is an extremely hard, low porosity plaster for casting, sculpting and case molds. A base Densite gypsum cement, this practical product provides low consistency in a neutral material.

It contains no accelerators, retarders or additives. Use Densite K-5 gypsum plaster cement in either straight-pour statuary or solid forms with predictable success. Used as a basic ingredient in dental stones, investment plasters, etc. Blend with a molding plaster or other general-purpose plaster to increase strength.

Helpful hints:

Always add plaster to water Avoid mixing air into plaster Water temperature affects the “set up time of plaster” (warm=faster / cold=slower) Use a clean container for mixing Keep unused plaster in airtight container Do not pour unused plaster down the drain 1 pt. water = 1 lb. water

What is the best cement mix for plastering?

OPC 43 is the best cement for plastering both exterior and interior walls of low residential buildings and OPC 53 is best for plastering high rise buildings. OPC is available in 3 grades in the market, OPC 33, OPC 43, and OPC 53.

What is the best cement ratio?

Ratios – If you do not get the ratio correct, then it can have negative consequences for your construction. For example, if you add too much water to the mortar mix, then it will not properly glue the bricks together. Then, over time the mortar will crumble and not withstand bad weather conditions.

On the other hand, if you add too much mortar mix, then the mortar might easily crack or shrink. Cracking can cause many problems for you in the long run. The best consistency of mortar for bricklaying is for it to be wet and thin. Only a small amount is used when layering. However, some jobs like fitting a roof may require it to be slightly thicker.

The standard ratio for average mortar mix is 3:1 or 4:1 for bricklaying. If you are using a pointing mix, then you should have a ratio of 1:4 or 1:5 mortar to sand. As for concrete, it depends on the strength you need it to be at. Usually, it is good practice to mix concrete at 1:2 mix to materials.

How many wheelbarrows of sand are in a bag of cement for plastering?
