Prestressed Concrete Design

Design of Reinforced Concrete Structures Concrete Concrete is a mixture of cement, fine and coarse aggregate. Concrete mainly consists of a binding material and filler material. If filler material size is < 5mm it is fine aggregate and > 5mm is coarse aggregate. Plain Concrete (PC) Mixt...

Definitions The water/cement ratio (w/c) is the weight of water divided by the weight of cement. When supplementary cementitious materials (SCM’s) are used, the w/c is referred to as the water/cementitious materials ratio (w/cm) and is the weight of water divided by the weight of cement and ...
