M−Sand is an artificial material made by crushing hard stones into fine particles, then washing and precisely grading them. For the experiment, three types of fine aggregates namely M sand, waste marble FA and waste granite FA are used. The specific gravity of M sand, Marble waste FA and granite waste FA are 2.5, 2.45 and 2.58 …

Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.
