Learn MoreNominal Concrete Mix Ratios. The specifications for concrete prescribed these proportions of cement, sand, aggregates, and water.. These mixes of the fixed cement, sand, and aggregate ratio that ensures adequate strength are termed nominal mixes.. Nominal concrete mixes offer simplicity and under normal circumstances, have a margin of strength above that specified.

Learn MoreThe basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10 ...
