Ready mix concrete is mixture of Portland cement, sand and aggregate with some admixture like accelerator, reducer, plastisizer. Each ingredients of concrete required in adequate quantities according to achieve targeted compressive strength or design of a concrete structure.

Ready mix concrete can be used for building or repairing foundation walls, fence post, sidewalks, curbs, steps and ramps and for setting posts and others concrete structure like, footing, slab, beam and columns.

Weight of a bag of concrete can varies in different country. In United State a bag of concrete available in different weight such as 90lb, 80lb, 60lb, 50lb & 40lb. In United Kingdom it is measured in Imperial and metric system in other countries. Others concrete bag size is 40kg, 30kg, 25kg & 20kg.

Weight of Ready mix concrete in dry condition is about 133 lbs per cubic foot, 3600 lbs per cubic yard, 17.826lb/gallon, 21.36kN/m3, 2.136kg/litre, 1.234 oz/ inch^3, 60kg/CF, or which is approximately equal as 2136 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.
