General Purpose Concrete – 20kg is a premix of cement, sand and aggregate ideal for load bearing, grey concrete applications where a 30MPa strength is required.

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.

Ready mix concrete can be used for building or repairing foundation walls, fence post, sidewalks, curbs, steps, shed floor, pergolas, concrete path 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.

A bag of 20kg concrete yields 0.009m3 volume that equates as volume of 9 litres which is approximately equal to 0.32 cubic feet or 0.0117 cubic yards.

In this articles you know about how many 20kg bags of concrete do i need. This will help to viewers in better understanding and it is easy to choose the most suitable bag size of concrete you wanted according to requirement.

**How many 20kg bags of concrete do i need**

A bag of 20kg concrete can can cover around 1.28 sq ft area for standard depth of 3 inch deep and it will required 110 bags of 20kg concrete to make 1 cubic metre.

How do i figure out how many 20kg bags of concrete i need depending on thickness of your slab and area of slab which on concrete is poured. Lets do calculation:-

**How many 20kg bags of concrete do i need**

1) Determine how thick you want the concrete, suppose thickness = 100mm, length = 5m and width = 4m

2) multiply the length and width of your slab to get square meter area 5m×4m = 20m2

3) Convert the thickness from mm to meter

Such as 100÷1000 = 0.1 meter

4) Multiply the thickness in meter by the square meters area to determine cubic meters of concrete you need such as 20m2 × 0.1m = 2m3

4) How many 20kg bags of concrete do i need is calculated by multiplying required concrete quantity (2m3) by No. of 20kg bag of concrete per m3 such as 2 ×110 = 220 bags

Thus, you will need 220 bags of 20kg concrete for 5m × 4m slab at 100mm thick.

**How many 20kg bags of concrete do i need?**

● To make 1m3 concrete = 110 bags

● To make 2m3 concrete = 220 bags

● To make 3m3 concrete = 330 bags

● To make 4m3 concrete = 440 bags

● To make 5m3 concrete = 550 bags

**Conclusion**:-

You will need 110 bags of 20kg concrete to make 1m3 of concrete, for 2m3 concrete 220 bags of will be required and to make 5 cubic metres of concrete you will need 550 bags of 20kg concrete.
