Light-weight Aggregate Prestressed Concrete
The use of light-weight aggregate concrete for prestressed concrete construction is well established. The main advantage of light-weight concrete is that it reduces the self-weight of the structural components. Because of this the amount of concrete and prestressing steel required for carrying the load is reduced. This type of concrete becomes important in long span structures where the self-weight of the member is an important factor to be considered for the determination of the design load of the structure. This eases the transportation of the members also.
