How do water-cement ratio and workability affect the strength of concrete? What are the factors promoting shrinkage?
w/c ratio is directly proportional to workability and inversely proportional to strength.
If w/c ratio is increased workability increased, which increase the ease and homogeneity with which it can be handled and mixed.
But as w/c ratio is increased the strength of concrete becomes poor.
Because proper proportion of water if not maintained in concrete mix, excess water accumulates in the mix and reduces the strength.
