It is recommended to use crushed sand. It is an economic and ecological alternative to natural sand. Crushed sand possesses properties similar to that of river and is a more sustainable construction material. Scientifically use of crushed sand will provide a long-term solution to construction industry to overcome shortage of river sand.
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
