Concrete Mix Design As Per Indian Standard Code. Concrete Mix Design As Per Indian Standard Code, determines the nominal water-cement ratio of the mix The other factor affecting the strength of concrete at a given age and cured at a prescribed temperature is the degree of compaction, alwys prefer M20 or M25 grade of concrete for columns,min M20 grade for columns Reply Link Rajat .
190 L. To find the design mix ratio, divide the calculated value of all materials by the weight of cement. Therefore Mix Design Ratio of M25 Grade concrete by weight is Cement: F.A: C.A: Water = 1: 1.9 :3.1 : 0.50. Note: This is a Design mix ratio by weight which is different from the Nominal volumetric mix ratio.
