Mix designs for concrete block
roportioning the mix components for a con-crete masonry unit (CMU) is an important step in producing high-quality units. A well-proportioned mix can improve a unit’s physical properties (compressive strength, unit weight, absorption) so they meet or exceed ASTM C 90 Standard Specification for Load-Bearing Concrete Masonry Units.
