Apr 19, 2014· Dear Habeeb, It is depend how much MPA for the concrete, higher concrete MPA need high rebar also. As my experience for Fc32 is200 -250 kg/m3. For Fc40 is200 -400 kg/m3, but these are not efficience. Normally the ideal is110-125 kg/m3. I hope this information useful for you. Thanks Andi
The weight of C.A. per cubic meter of concrete is calculated by multiplying the bulk volume with bulk density. From Table 11.4, for 20 mm coarse aggregate, for fineness modulus of 2.80, the dry rodded bulk volume of C.A. is 0.62 per unit volume of concrete. The weight of C. A.=0.62 𝑥 1600= 992.0𝑘 3

Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft).

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.
