STRENGTH AND DURABILITY PROPERTIES OF HIGH

Manufactured Sand (M-Sand) produced by the crushing of hard granite has been identified as a good substitute for natural sand. The main objective of this study is to check the strength and durability characteristics of HPC using M-Sand along with 5% silica fume. The natural sand was replaced by M-Sand on proportion of 0%, 20%, 40%, 60%, 80% and 100%. The

Aggregate Properties You Need to Know:

Construction aggregates are extracted from natural sand and gravel deposits or quarried from rock formations. The raw, mined materials are crushed to suitable sizes if required, then sorted by size and shape for use as fine or coarse fractions. These mining operations produce some 2.5 billion tons of construction aggregates annually for the U.S. domestic market. Manufactured aggregates are a ...
