WATER AND ITS ROLE IN CONCRETE. PART 1 OF 2

The importance of the role of water in concrete is discussed, and its beneficial and destructive properties are noted. The mix water quality is discussed, as well as the relative properties of fresh water and non-fresh water. The temperature of water affects its freshness and the amounts of dissolved chemicals. Water alkalinity increases considerabley upon contact with cement, and the fresher the cement, the faster will be the rate of reaction. The effects of organic matter, admixturues, how to cope with impure mix water, and mix water quantity are discussed. The free water demand increases as the aggregate size decreases. Aggregate angularity and grading compatibility, aggregate absorption, and aggregate/concrete density are discsussed, as well as workability and cement type, cement content, and temperature.
