Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregat For eg, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate
CONCRETE MIX DESIGN The following describes the Standard Practice for Selecting Proportions for Normal, Heavyweight, and Mass concrete based on a report published by the American Concrete Institute (ACI), Committee 211 The Standard (ACI 2111-91, Reapproved 2009) has been approved for use by agencies of the Department of Defense .
