Concrete Mix Ratios Cement, Sand, Aggregate and Water

03/12/2014 The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed. Concrete mix ratio of 1:3:3 On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three

1m3 of concrete material cement sand aggregate and water

M20 concrete mix ratio is 1:1.5:3 made of mixture of cement, sand, aggregate and water in which 1 part is cement, 1.5 part is sand and 3 part is aggregate. Sum of ratio 1+ 1.5 +3 = 5.5, part of cement =1/5.5, part of sand=1.5/5.5 and part of aggregate = 3/5.5. You Can Follow me on Facebook and Subscribe our Youtube Channel. You should also visits:-
