Density vs Strength: There's a Difference Basalite CMU

2018-7-24  The Compressive Strength of CMU is measured in “pounds per square inch”, (“lbs/in2” or “psi”). Among the combined strengths of the aggregates, sand and cement, the more important influence on overall compressive strength is the quantity of cement used in the mix, and the time allowed for the block to cure. Generally, the higher the cement content, the higher the strength, and, the longer the CMU cures, the stronger it gets, until it reaches its maximum designed strength
