To make 1 cubic meter of concrete, the typical mix ratio for a standard concrete is about 1 part cement, 2 parts sand, and 3 parts aggregate (1:2:3). This means you would need approximately 350 kg of cement, 700 kg of sand, and 1050 kg of aggregate. The total volume for these materials should add up to 1 cubic meter when factoring in the mixing process and compaction. Adjustments can be made based on specific project requirements or desired concrete strength.
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.

To make 1 cubic meter of concrete, you typically need about 1.5 cubic meters of sand and gravel combined. The general ratio for mixing concrete is 1 part cement, 2 parts sand, and 3 parts gravel. Therefore, for 1 cubic meter of concrete, you would need 0.5 cubic meters of cement, 0.75 cubic meters of sand, and 0.75 cubic meters of gravel.
1) weight of cement in one cube divided by density of cement = volume of cement in a cube: 2) Similarly volume of fine & Coarse aggregate can be calculated 3) Adding all one will get volume of solids in a Cube-Vs: 4) Subtracting Vs from volume of cube Vc one would get volume of voids Vv 5) taking ratio of Vv to Vs one would get void ratio

For 1 meter cube of brick work, you would need approximately 13 bags of cement.

A metre cube of concrete is a volume of concrete which is equivalent to the volume of a cube each of whose sides are 1 metre long.
