cement per unit volume of the concrete is found by dividing the estimated water content by the w/c ratio. weight of water weight of cement wc Mix Design Procedures However, a minimum cement content is required to ensure good finishability, workability, and strength. ACI Mix Design 7. Estimation of coarse aggregate content The percent
Finally, C = Kg / m 3 of concrete. But from table 5 of IS, Minimum cement content required for moderate exposure condition for M15 grade concrete is = 240 Kg/m 3 of concrete. Greater of above two values will be the cement content. Hence, C = Step 6: Aggregate Ratio for Concrete
Water Cement Ratio means the ratio of the weight of water to the weight of cement use in concrete mixture. Or in easy words it is the amount of water required in the cement concrete mixture. As we know that water cement ratio directly affects the strength of concrete. So, by being in limits of [.]
