Rate Analysis of Reinforced Concrete Structures
Data required for RCC Rate Analysis: 1. Estimation of materials : Material estimation include sand, cement, coarse aggregate and steel for a particular mix design. Let us consider a mix design of 1:1.5:3 for our estimation practice. The dry volume of total materials required is considered as 1.54 times the wet volume of concrete, due to voids present in sand and aggregates in dry stage. Therefore, for our calculation, we will consider the total volume of materials required as 1.54 m3 for 1 m3 of wet concrete. a) Bags of cement required: Volume of cement required for 1m3 of Concrete =1.54/5.50 =0.28 m3 Then number of bags of cement (volume of one bag of cement = 0.0347 m3) =0.28×0.0347= 8.07 bags of cement. b) Volume of Sand required: Volume of sand required =1.5×0.28 = 0.42 m3 of sand. c) Volume of Coarse Aggregate Required Volume of Coarse Aggregate =3×0.28= 0.84 m3 of coarse aggregates. d) Estimation of Reinforced Steel: Quantity of steel required ...
