Light Weight Aggregate Concrete
Chapter no. 1 For about half of a century concrete has been a material of choice for mankind. This popularity of concrete is due to some of its excellent properties in fresh and hardened state. Concrete is by far a cheaper material to produce when compared with its competitors (steel and Aluminum), it is easy to manufacture and does not require specialized techniques for its production, concrete has excellent resistance to weathering effects, it has high thermal mass and offers good insulating properties. In everyday life its use span from ornamental purposes to the construction of heavy structures including multistory buildings, bridges, water retaining structures and nuclear power plants. Among above properties of concrete, one of its useful characteristic is its resistance to the transfer of heat. Thus concrete insulates steel when used in reinforced concrete construction and protects it against the effects of environmental changes. The insulating property of the concrete can ...
