how to calculate 1:2:4 ratio concrete cement, sand, metal
and water please give me brief calculation
Answer Posted / farhan tanoli
In order to estimate the quantity of loose materials to have
100 cubic feet wet concrete we first multiply the wet
concrete by 1.54.
e.g 100x1.54=154 cubic feet of dry materials we need.
now come to the ratio of concrete which is 1:2:4 so sum of
the ratio will be 1+2+4=7
calculating separately each material:
Cement: 1/7x154 = 22 cubic feet
where 1 bag of cement measured 1.25 cubic feet approx
therefore 22/1.25 = 17.6 bags of cement. 1 bag contains 50kg
cement so total cement by weight we need for 100 cubic feet
concrete = 17.6x50 = 880kgs
sand: 2/7x154 = 44 cubic feet
coarse aggregate: 4/7x154 = 88 cubic feet
