Prestressed Concrete

          Prestressed concrete, the improved condition of RCC (Reinforced cement concrete) where steel is used as both compression and tension member.
Prestressed concrete

       Prestressed concrete is used in structure where higher load is to be sustained such as bridge, arch structure etc. Addition bars are used in tension face of Reinforced Cement Concrete (RCC) member which kept upon tension at the beginning of casting. After casting of the member the tension is to be cut of which tends to compress again. Thus extra compression is imposed on the tension face of the member which eventually increases the tension capacity of the member. Thus, the basic difference between RCC member and prestressed member is that, addition compression is added in the tension face which rises the capacity then simple RCC member. Thus the concrete is prestressed.
