WHAT IS GRADE OF CONCRETE? Grade of Concrete is denoted by : M5 , M7.5 , M10 , M10 , M15 , M20 , M25 , M30 , M35 , M40 , M45 ect are the compressive strength of concrete. So here “M” Stands for Mix And “Number” shows the Show N/mm2. For Example M25 Grade of concrete Compressive strength is 25N/mm2.

USBR method of concrete mix design. The M35 and M40 grades of concrete were compared for design by ACI and USBR method using stone dust as fine aggregate. The result indicates that the concrete designed with. USBR method using stone dust gives maximum results in compression, flexure and split tensile strength.
