Question

What is the effect of water cement ratio on strength of concrete?

Answer 1

The water cement ratio is the ratio of the weight of water to the weight of cementused in a concrete mix and has an important influence on the quality of concrete produced. A lower water-cement ratio leads to higher strength and durability, but may make the mix more difficult to place.

Answer 2

Explanation:

If the water-cement proportion is higher, it brings about wider spacing between the cement aggregates and thus, influences the compaction. Correspondingly, concrete's durability and compressive strength are decreased due to increased dampness levels.
