How much sand and gravel do you need to make 1 cubic meter of concrete?

Answer 1

The Question is mistake. The Question is How much sand and aggregate required for the one cubic meter of M20 grade concrete? Answer :- 20mm aggregate = 0.90M3 Sand = 0.45M3 to 0.5M3 depond on the Bulk density of Sand Cement = 320kg

Answer 2

FOR 1cubic meter of concrete block ,firstly we must know the mix ratio but if e.g we have the ratio of 1:2:4 ,

1 is cement

2 is sand

4 is aggregate

than we need these quantities for 1 meter cube

0.22 cubic meter cement which is 6.28 cement bags

0.44 cubic meter sand

and 0.88 cubic meter aggregates

Answer 3

To make 1Cubic Metre of Concrete you use 1 Cubic Metre of Crushed Rock or other coarse aggregate. You then add 1/2 cubic Metre 'washed sand', and 1/4 cubic Metre Portland Cement. Mix thoroughly while still dry then add the water progressively to the desired sloppiness.this gives the strongest concrete. The fact is, that all the sand and all the cement you add, simply fills up the air spaces between the pieces of crushed rock. So for 3 cubic Metre of Concrete you need the same volume of crushed rock, then half as much washed sand and one quarter as much cement.. The RATIO is 4:2:1 always. Bricklayers sand is not suitable because it contains clay and sometimes a little soil as well. It is very common to use the Ratio 5:2:1 for a cheaper slightly weaker concrete, and sometimes the Ratio 5:2&1/2:1 but 4:2:1 is ideal and most common. Concrete should be kept wet for at least 3 days to ensure it cures to a good strength. In hot weather hose the surface several times aday to keep it wet to encourage good strength or cover it from the hot sun with wet hessian, or white, heat reflective, plastic.
