Concrete Trial Mix » Construction+Nigeria

For test performed on each sample, 6 cubes are required to be made, one set for crushing at 7 days and another set for crushing at 28 days. For a good concrete mix design, it should be noted that the compressive strength on compression measured in N/mm 2 after 7 days should be around 75% of the target strength i.e. strength after 28 days.
