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.
found and the mix design requires adjustments to compensate for variations from the ideal conditions. The consistency of the mix, relative to the wetness or dryness, will affect the workability to a large degree. Do not increase the water content beyond the tolerance allowed in Specification 2461.3J without adjustment in the mi x design.
Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. The Advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.
