The cement ratio of M25 concrete is 1:1:2

• The cement ratio of M25 concrete is 1:1:2, which means 1 part cement, 1 part sand, and 2 parts aggregate.

• This ratio is commonly used for construction projects requiring a medium strength concrete mix.

• It is important to follow the correct ratio to ensure the desired strength and durability of the concrete.

Circular concrete quantity can be calculated by finding the volume of the concrete needed for the circular shape.

• Calculate the area of the circular base by using the formula: Area = πr^2 (where r is the radius)

• Determine the height of the concrete structure

• Calculate the volume of concrete needed by multiplying the area of the base by the height

• Consider any additional factors such as thickness of the concrete slab or wal...read more

The ratio of M20 concrete is 1:1.5:3 (cement:sand:aggregate).

• The ratio of M20 concrete is 1:1.5:3, meaning 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• This ratio is commonly used for construction of residential buildings, pavements, and small industrial structures.

• It is important to follow the correct mix ratio to ensure the strength and durability of the concrete.

The ratio of M10 concrete is 1:3:6 (cement:sand:aggregate).

• M10 concrete has a mix ratio of 1:3:6 (cement:sand:aggregate).

• This means for every 1 part of cement, 3 parts of sand and 6 parts of aggregate are used.

• The strength of M10 concrete is lower compared to higher grades like M20 or M30.
