The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first. The cubes are

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 …
