Concrete Mix 124 Strength

concrete mix design for normal strength concrete,adjust for moisture content in course and fine aggregate. example: design a concrete mix for 4000 psi concrete strength, beam, and a maximum size of aggregate = ¾ in, with fineness modulus of sand = 2.6, the dry rodded weight of aggregate = 100 lb/ft 3, and a moisture content of 3% for the coarse aggregate and 2% for the fine aggregate..how to correctly mix concrete? concrete mix ratio - dtm,the c20 concrete mix is a medium-strength concrete recommended for basic household constructions such as retention of posts, garden walkways and many more. this cement and sand mix is, however, not recommended for use in constructing a foundation and other construction works that would need super resilient concrete..
