    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 ...

    The idea of prestressed concrete has been around since the latter decades of the 19th century, but its use was limited by the quality of the materials at the time. It took until the 1920s and ‘30s for its materials development to progress to a level where prestressed concrete could be used with confidence. Freyssinet in France, Magnel in
