The Effect of Aggregate Properties on ConcreteCalculate Quantities of Materials for Concrete -Cement

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concreteFa = Mass of fine aggregat Ca = Mass of coarse aggregat S c, S fa and S ca are the specific gravities of cement, fine aggregates and coarse aggregates respectively The air content has been ignored in this calculation This method of calculation for quantities of materials for concrete takes into account the mix proportions from design mix or nominal mixes for structural strength and.
