Concrete mix ratio

The proper concrete mixing ratios are 1:2:3, 1:3:3, 1:2:4 for cement, sand, and stone. Mixing ratios are based on what psi concrete you need. Mixing ratio chart

In this article, we explained how to determine the concrete mix ratio in relation to the number of head pans of sands and gravels that are actually needed for a bag of cement and How much sand and gravel need for a bag of cement.

How to calculate cement, sand and aggregate required for 1 cu.m of concrete (Concrete Mix Design). Different grades of concrete and how to chose the grade

That's 8 bags of cement, 15 CFT of sand and 30 CFT of aggregate are required for one cubic meter (1m3) of M20 concrete. A typical M20 grade of concrete requires 8 bags of cement, 15 CFT of sand and 30 CFT of aggregate per cubic meter.

If you avoid these common mistakes, the concrete will look great and last for decades.

The key to achieving the psi strength labeled on a bag of concrete is keeping the water-to-cement ratio as low as possible without sacrificing workability. Adding too much water can cause a host of problems. - Fine Homebuilding
