When salts are applied to concrete, they attract up to 10% more water into the pore structure of the concrete.

A.: Fly ash is used in concrete for flatwork to permit use of lower cement contents and to enhance workability. The proportioning of mixes containing fly ash should not be based on the simple replacement of a percentage of the cement by an equal percentage of fly ash, a practice all too commonly used.
By Absolute Volume of Ingredients Yield of concrete can be calculated more accurately by considering the absolute volumes of various ingredients used in concrete (cement, sand, coarse aggregate & water) with volume of entrapped air. When concrete is well compacted, the volume of entrapped air is less than 1% and therefore, it can be neglected.
