This website uses cookies to improve your experience while you navigate through the website. Copyright Policy | The data required for mix proportioning is as follows. In this design project we have designed M60 grade concrete using Design mix of American Concrete Institute method, and also found out compressive strength for design mix method. As for instance a concrete mix of proportions 1:2:4 signifies that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix comprises of one part of cement, two parts of fine aggregate and four parts of coarse aggregate. Maximum nominal size of aggregates 4. NBMCW October 2015. “M” stands for “mix”. Actual microsilica used = 40 kg/cum The Mix Proportion for M100 grade concrete is derived as 1 : 0.617 : 1.644 by following the design procedure given by ACI Method. In concrete grades, the letter “M” stands for “Mix” and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test. Plz i need.
