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 []

Learn MoreNOTES: 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.

Learn MoreOne 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

Learn MoreMar 31, 2020 · Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer. Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar - 1 part cement, 4 to 5 parts building sand. Alternatively, one can also use 1 part cement, 1 part lime and 4 to 5 parts building sand.

Let us assume a standard quantity of 1m 3 Cement mortar and a mix proportion of CM 1:6 (1 part Cement & 6 parts Sand). The quantity can calculated in two ways, one is by weight and the other by volume.

Learn MoreApr 12, 2018 · A typical concrete mix contains 60 to 80 percent sand and gravel, also known as an "aggregate." This aggregate compound is more than filler. It plays an important part in the concrete's composition. The amount of sand and gravel in a bag of concrete

Learn MoreFirst 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.

Learn MoreThe 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.
