Read moreSep 25, 2017· Concrete Mix Proportions Notes to Remember. 1) The more rock, the greater the compressive strength of concrete. The more sand, the greater the workability. 2) Adhesion (cement) and compressive strength (rock) are two different factors in the quality of concrete. More cement does not mean more compressive strength; it means more tensile strength.

Read moreThe nominal mix is the prescriptive type concrete because a proportion is pre-decided. 02. It is easy to make at the construction site. 03. It doesn't take much time to decide the proportion because proportions are already given by standard code. 04. No need to get skilled persons for making the nominal mix concrete.
