This is especially true for industrial buildings, where the environment could be contaminated with aggressive products or waste. An important issue is ...
A rectangular reinforced concrete slab is simply-supported on two masonry walls 250 mm thick and 3.75 m apart. The slab has to carry a distributed permanent action of 1.0 kN/m2 (excluding slab self-weight) and a variable action of 3.0 kN/m2. The materials to be used are grade C25 concrete and grade 500 reinforcement. The slab is outside ...
For calculation, We consider a nominal concrete mix proportion of 1:2:4 (~M20). Step-1: Calculate Weights of Materials Required To arrive at different quantities of concrete ingredients, the Dry loose bulk density of materials plays important role as they are batched loosely.
