Allowable Wastage Of Construction Materials

Cement: 2% to 3.5%: Due to the fineness of cement, it may fly away by air when cement mixes with the other ingredients. Sand: 8% to 12%: The sand is sieved for plastering work and other finishing works. So some coarser sand will be neglected while sieving and some particles are dropped off during transportation. Coarse Aggregates: 5% to 8%

Types and Causes of Concrete Deterioration

Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2).
