ACI mix design Memphis
ACI Mix Design A measure of the degree of consistency and extent of workability is the slump. In the slump test the plastic concrete specimen is formed into a conical metal mold as described in ASTM Standard C143. The mold is lifted, leaving the concrete to "slump," that is, to spread or drop in height. ACI Mix

This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent.
