For M-20 grade concrete, the mix ratio is typically 1:1.5:3 (cement: sand: aggregate) by volume. To determine the amount of cement needed, you can use the total volume of concrete required. For example, if you need 1 cubic meter of M-20 concrete, you would need approximately 0.5 bags (around 50 kg) of cement, as cement constitutes about 10-15% of the total volume in this mix. Always consider adjusting the quantities based on specific project requirements and local material properties.
