desired workability and 28-days compressive strength of concrete for a particular . Provision of minimum cement content and maximum water cement ratio ensure .. M25. 4.3. 5.3. 6.3. M30. 5.0. 6.0. 7.0. M35. 5.3. 6.3. 7.3. M40. 5.6. 6.6. 7.6.
Dec 29, 2011 . We have to define concrete by unit contents of concrete and w/c ratio, . aggregate:Coarse aggregate) M15 - 1:2:4 M20 - 1:1.5:3 M25 - 1:1:2
M20-M25: 4.0 MPa. M30-M50: 5.0 MPa . contents for concrete grades up to M35/ above M35 . Step 4: Calculate cement content,. Aggregate contents,. ❖ w/c*=.
Dry volume of concrete in 1cum=1.54. Cement Quantity=1.54/(1+1.5+3) =0.28cum =0.28/0.035=8 bags =0.28*1440=403.2kg same way we can calculate M25.
c) Maximum water-cement ratio and/or maximum cement content to give adequate . M25 correspond approximately to the mix proportions (1:3:6), (1:2:4),.
So, for preparing 1cu.m of M25 concrete, quantity (dry volume) of cement required = 1.55 . there are two methods of determining the minimum cement content .
c) Maximum water-cement ratio and/or maximum cement content to give . the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and.
