2018-1-17 The concrete mix ratio refers to the proportion of the components in the concrete. The concrete mix ratio is usually represented by the quality of various materials per cubic meter of concrete, or amount proportion of various materials. The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design.
