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 "Mix" is the respective ingredient proportions which are Cement Sand Aggregate Or Cement Fine Aggregate Coarse Aggregate What Is The Compressive Strength Of M40 ConcreteCompressive Strength of Concrete Hardened Concrete 1 sivakumar +91 9790 777000 Get Price What is the ratio of Grades M10 M15 M20 M25 M30 M35 M40 57 Calculate the volume of a truck loaded with stone chips whose data are as follows– 5 Top Length Flexural Strength of BeamsThe average 28 days compressive strength for different proportions of concrete mixes shown in fig The results show that the compressive strength of concrete is increased as copper slag quantity increases up to 40% addition beyond that the was reduced due to comp strength significant increase in free water content in the mixes
