M30-Grade Concrete Cement Sand And Aggregate Mix Ratio

For M30-grade concrete, assuming a standard deviation of 5 MPa, the target mean strength is calculated as follows: Mean target strength=30 MPa+1.65×5 MPa=38.25 MPa. Water-Cement Ratio Selection: The water-cement ratio is determined depending on the target mean strength and required workability. The cement-water ratio is typically between 0.40 ...

What is the mix ratio for C20, C25, C30, C35 and C40 concrete

The common concrete mix ratio to create C25 grade of concrete is 1 : 1.40 : 2.85 : 0.47, (cement: Sand: Stone: water) by weight. This means, 1m3 of C25 grade of concrete can be prepared by mixing of 1 part of cement (415kg of cement) + 1.40 parts of Sand (583kg of Sand) + 2.85 parts of Stone (1184 kg gravel) + 0.47 parts …See more on civilsir
