Density of cement = 1440 kg/m³. To calculate the quantity of cement required, we can use the following formula: Quantity of cement = (Proportion of cement / Total proportion) x Volume of Dry mix concrete. Quantity of cement = (1 / 5.5) x 1.54 = 0.28 m³. Weight of cement per m³ = Density of cement = 1440 kg.

more water, cement or sand as needed. Concrete must be used within 2 hours of mixing, the sooner the better. Avoid over-working any poured concrete, as this will weaken the concrete. Sand shrinks in volume when water is added, so order a little more than the dry volume. Best time to work concrete is early morning or late afternoon, but be aware
