The mix ratio of M20 grade of concrete is 1:1.5:3.

• The mix ratio of M20 grade of concrete means the proportion of cement, sand, and aggregate used in the concrete mix.

• For M20 grade concrete, the mix ratio is 1 part cement : 1.5 parts sand : 3 parts aggregate.

• This means that for every 1 part of cement, 1.5 parts of sand, and 3 parts of aggregate are used.

• For example, if you have 1 bag of cement (50 kg), you would need 1.5 bags of sand (75 kg) and 3 bags of aggregate (150 kg) to...read more
