To do this, multiply the total volume of concrete by the proportion of metal in the mix ratio. For example, for a 1:2:3 mix ratio, the proportion of metal would be 3/(1+2+3) = 3/6. So, the volume of metal needed would be: Volume of metal = 1m³ x 3/6 = 0.5m³. Step 5: Convert the volumes of cement, sand, and metal into weights.

One of the best mixture ratios for a concrete slab is 1 : 3 : 3 (cement : sand : stone), this will produce approximately a 3000 psi concrete mix. This mixing ratio is excellent for a shed slab, but it's also good for most concrete patios, footings, steps, and foundation walls. The proper mixture of … See more

# Mix Portland cement and sand at a 1:2 or 1:3 ratio in your mixing container. The 1:2 ratio will yield concrete with about a 3500 pound per square inch compression stress. The 1:3 ratio will yield somewhat less than 3000 PSI, which is typical for house slabs, footings, and sidewalks. NOTE: Although it
