Methods of Proportioning Cement, Sand and Aggregates in Concrete

Proportioning of concrete is the process of selecting quantity of cement, sand, coarse aggregate and water in concrete to obtain desired strength and quality. The proportions of coarse aggregate, cement and water should be such that the resulting concrete has the following properties: When concrete is fresh, it should have enough workability so that it can []

Recommended Concrete Mixes for Various Types of Construction

NOTES: When both fine and coarse aggregates are poorly graded, the following general rules regarding suitable proportioning of these will be found helpful: For maximum size of coarse aggregates as 40mm and over, sand should be half as much as coarse aggregates. For maximum size of coarse aggregates as 20mm and over, sand should be two-thirds as much as coarse aggregates.

How to Calculate Quantities of Cement, Sand and Aggregate for

One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft. Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft

mortar - What's the best ratio for sand-only concrete

First I want to point out that the hardness has a lot to do with cure time and temperature. Longer cures (6-8 weeks) at cool temperature (say 50 °F) are harder. Short, hot cures are harder initially, and crumble later. Generally, the 1pt cement : 2pt sand ratio is best and will have a 3500 psi compression stress.

Effect of Fineness of Sand on the Cost and Properties of

The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from 2.0 to 3.0. That means we can get large advantage by using concrete having Coarse Sand.
