The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume. 1 : 1 : 2 and 1 : 1.2 : 2.4 for very high strength. 1 : 1.5 : 3 and 1 : 2 : 4 for normal works. 1 : 3 : 6 and 1 : 4 : 8 for foundations and mass concrete works. Recommended Mixes of Concrete. The concrete as per IS 456: 2000, the grades of ...
M20 (1 cement :1.5 sand :3 stone/brick aggregate). To determine the proportions you have to perform mix design, for this you have to find out the sp.gr. of cement, CA, FA, and water cement ratio ...

While the U.S., U.K. and a few other countries use psi, the majority of countries rely on MPa. Many manufacturers, builders and suppliers provide product data showing both MPa and psi ratings for concrete materials. To convert psi to MPa, multiply the psi value by 0.0068915. For example, 2,500 psi = 2,500 x 0.0068915, or 18 MPa.
Hi , We use minimum grade of concrete for RCC = M20. For M20 , GRADE = 1:1.5:3 Volume of Concrete = L x B x D= 1 cum. Wet Volume of concrete = 1 cum Dry volume of concrete = 1.52 x 1 = 1.52 cum. Ratio = 1:1.5:3 = 5.5 * Cement = 1.52[ 1/(1+1.5+3)] ...
May 17, 2017· Concrete Mix Design:-Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Accurate concrete mix design makes concrete construction economical.
For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

Therefore, thesand/gravel ratio was controlled in the range 28–32% during mixing. By adjusting the ratio of water/cement, amount of aggregates, ratio ofcement/sandand mix proportions of additive, an increasing strength and good performancemortar and concretecould be obtained. 4.

Feb 01, 2015· Hi all, I have approx 12 stump holes to fill with concrete to support stirrups. I have 1.5 cubic meters of crushed rock sitting in the back yard and the 12 holes are in the back corner of the block so think it will be easier for me to hire acementmixer and mix thecement…
First you have to excavate to a solid ground, ideally clay,sandor rock. Work out your finish floor level. I would build my cabin above ground level to avoid flooding and damp. Allow for 100-150mmof sub-base ( compacted Mot) minimum. If more than that, compact it in layers (150mmmax).
The grade of concrete for various concrete proportions are M10 - 1:3:6 (Cement:Fineaggregate:Coarseaggregate) M15 - 1:2:4 M20 - 1:1.5:3 M25 - 1:1:2 Among these use M20 grade that should be ...
