7.1 Introduction. Plain concrete is a brittle material, with low tensile strength and strain capacities. The use of short, discontinuous fibres to strengthen and toughen such materials, which are much weaker in tension than in compression, goes back to ancient times. Probably the oldest written account of such a composite material (clay bricks ...

Therefore volume of 1 bag cement = 50/1440 =0.0347 cum. ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags.

mass = density × volume The density of plain cement concrete is 2400 kg/m³ (see the densities table below). The volume we want to convert is 1 cubic meter. Now, plugging these values in the formula above, we get: mass = density × volume = 2400 × 1 = 2400 So, 1 cubic meter of plain cement concrete equals 2.4 × 10 3 kilograms Kg.
Get priceThis indicates that the wet curing time has a greater influence on concrete containing mineral admixtures than plain cement concrete.Two reasons may account for it: (1) when wet curing is insufficient (only 2 days), the reaction degrees of GGBS and fly ash are low, which makes their pore structures coarse and the connected porosity increases at late age.
