Tables 9-1 and 9-2 show requirements for various expo- sure conditions. When durability does not control, the water-cementi- tious materials ratio should be selected on the basis of concrete compressive strength. In such cases the water- cementitious materials ratio and mixture proportions for the required strength should
With advent of new generation admixtures, it is possible to achieve higher grades of concrete . the strength of concrete for the same water/cement ratio. . 1970 - table 2, Clause 4.1 and 4.2 (Refer Annexure I page 57 of Durocrete Mix. Design Manual) for single size aggregate as well as graded aggregate. The grading.
6 Sep 2016 Concrete Mix design calculation of M20, M25, M30 grade of concrete with example. Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. Maximum water-cement ratio for Mild exposure condition = 0.55.

the type of fine aggregate,. – the maximum size of aggregate,. – the overall grading, and. – particle shape and surface texture, have little direct effect on the compressive strength. • Typical strength values when uncrushed or crushed coarse aggregates are used are given in Table 2.
