Table 7. — Quantities required for 1 cubic yard of concrete for various mixtures. 
[Based on one barrel of cement being equal to 376 pounds, or 4 bags of 94 pounds each, and a barrel equal 
to 3.8 cubic feet and using stone, 45 per cent voids.]

A very handy formula for finding the amount of material to 
make 1 cubic yard of concrete is: 
The barrels of cement in 1 cubic yard = p, o , p 
Example : 
Barrels of cement to make a cubic yard of 1:2^:5 mixture = 
11 
1+21 + 5 
1.3 barrels. 
To find the cubic yards of sand: Multiply barrels of cement by 
proportional part of sand and the product by 0.141. Example: 
1.3X2JX0.141 = 0.458 cubic yards of sand. To find the cubic 
yards of stone, multiply the barrels of cement by the proportional 
part of stone and the product by 0.141. Example: 1.3X5X0.141 = 
0.916.
