Concrete used for construction of residential, commercial and industrial structure, several projects like bridge, dams, reservoir, Highway Roadways driveway, french drainage system, patio, tunnels, base for retaining walls, drain construction, pavement, road, street, walkaway, and used for slab etc.

Concrete ready mix made of blended mix of Portland cement, sand gravel and other approved ingredient in a required proportion to achieve desired strength, concrete slab are used in patio making, walkway, driveway etc.

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

For small project, it is better to use concrete bag. A bag of concrete have different weight such as 10kg, 20kg, 25kg, 30kg, 35kg and 40kg, which are used for many repairing work or new small projects, like patio, sidewalk, rampe etc.

The volume of concrete measured imperial and metric units, like in cubic meters, cubic feet, cubic yards, litres, gallons and cubic inches. Weight of concrete measured in kilograms (kg) and pound (lb) also.

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 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/ inch3, 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.

Metric density of Mix bag is around 2130 kg / m3 (2110 kg / m3 to 2150 kg / m3) and imperial density is about 133 lbs / ft3 (130 lbs / ft3 to 135 lbs / ft3). Metric density for structure 2300 kg / m3 (2240 kg / m3 to 2400 kg / m3) and for Reinforced concrete (ex slab or counter) 2400 kg / m3 (2300 kg / m3 to 2500 kg / m3).

**How much concrete does a 25 kg, 20 kg, 30 kg & 40 kg bag make**

To calculate yields of a concrete bag, divide weight a concrete bag by 2130 to get volume a concrete bag in cubic meters. Resulting figure Multiply by 1000 to get volume in litre.

A 25 kg bag make 0.0117m3, or 11.7 litres of concrete. A 10 kg bag make 0.00469m3, or 4.69 litres of concrete. A 20 kg bag make 0.00938m3, or 9.38 litres of concrete. A 30 kg bag make 0.014m3, or 14 litres of concrete. A 35 kg bag make 0.0164m3, or 16.4 litres of concrete. A 40 kg bag make 0.0187m3, or 18.7 litres of concrete.
