    Abstract - (Show below) - (Hide below)

    Deals with the design, materials and construction of buildings and structures in reinforced concrete, prestressed concrete and precast concrete. It is written in limit state terms. Guidance is given on the specification and workmanship of concrete, the inspection and testing of structures and the fire resistance of various forms of construction.
