Explain water cement ratio in concrete? What you will recommend if cube strength differ 12% ?

Question

Accepted Answer

Water cement ratio in concrete is the ratio of the weight of water to the weight of cement used in the mixture.

Water cement ratio is an important factor in determining the strength and durability of concrete.
A lower water cement ratio generally results in higher strength concrete.
If the cube strength differs by 12%, it indicates a significant variation in the concrete mix.
To address this, the water cement ratio can be adjusted to achieve the desired strength.
For example, if the cube strength is lower than expected, reducing the water cement ratio can help improve the strength.
On the other hand, if the cube strength is higher than expected, increasing the water cement ratio may be necessary to achieve the desired strength.

Accepted Answer

Recommended water cement ratio for concrete

If required higher quality concrete 0.6,0.7

Accepted Answer

Typically mix is about 10,15 percent cement

Water percent 15,20
