Jan 15, 2016Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine. Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone.

Aggregates Sand, Gravel and Crushed Stone Aggregates, which consist of crushed stone, sand, and gravel, are among the most abundant natural resources and are a vital raw material used by construction, agriculture, and industry. Aggregates are fundamental to our lifestyle. Imagine our lives without roads, bridges, streets, bricks, concrete, wallboard, and roofing tiles or without []

Joint sand provides vertical interlock and shear transfer of loads. It can be slightly finer than the bedding sand. Gradation for this material can have a maximum 100% passing the 1.25 mm sieve and more than 10% passing the 80m sieve. Commonly the bedding sand is used for the joint sand for easier control of job site materials.
