Normal grade of concrete are M25,M20,M15,M10,M7.5 & M5 generally based on nominal mix proportion of cement sand and aggregate.. Standard grade of concrete are M25,M30,M35,M40,& M45 are made according to design mix have higher compressive strength than normal grade of concrete.

M25 grade concrete, unlike M15 and M20, is a standard type of grade concrete.M25 grade concrete is a higher grade concrete than M20. PROPERTIES OF THE M25 GRADE CONCRETE: M25 is a mixture composed of cement, fine aggregates and coarse aggregates with a ratio of 1:1:2 is 1cement, one sand, and two aggregates.

Sand provides bulk, strength, and other properties to construction materials like asphalt and concrete. It is also used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a moulding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper.
