Concrete Technology, Lectures Course Notes on

Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known ...
