For example, let's calculate the amount of cement, sand, and gravel for the M5 mix to fill one cubic yard of space. Start by calculating the dry volume of the mix. dry volume = 1.0 × 1.54 = 1.54 cu yds. Recall the percentages for this mix are: 1 part cement -> 1/16 = 0.0625 5 parts sand -> 5/16 = 0.3125 10 parts gravel -> 10/16 = 0.625. Now, multiply each of …
