FACTORS TO BE CONSIDERED FOR MIX DESIGN The grade designation giving the characteristic strength requirement of concrete. The type of cement influences the rate of development of compressive strength of concrete. Maximum nominal size of aggregates to be used in concrete may be as large as possible within the limits prescribed by IS 456:2000.
Abstract: The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. From the result of the sieve analysis, it shows that the sands used for the experiment is a well graded sand of zone 1 of BS882 parts 2 (1973).
Grades of Concrete. Actually, what do we mean by grade of concrete.? Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The “M” denotes Mix design of concrete followed by the compressive strength number in N/mm 2
