Aggregates for Concrete - Memphis

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

The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6.And if M x is within 3.7 ~ 3.1, it is coarse sand; if M x is within 3.0 ~ 2.3, it is medium sand; if M x is within 2.2 ~ 1.6, it is fine sand; and if M x is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is
