Aggregates for Concrete - Civil Engineeringinvaluable in evaluating aggregates. In the absence of a performance record, the aggregates should be tested before they are used in concrete. The most commonly used aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight).tests for crush stone pdf,comparison study on natural river sand and crushed stone sandsCrushed Stone Sand. This study covers testing of all physical and chemical parameters of fine aggregates and their effects on concrete properties –workability, pumpability , setting time & compressive strength and also durability tests on concrete with M. sand. Methodology of the study: M25 grade and M40 grade concretes.

Gravel - Wikipedia

Crushed stone: rock crushed and graded by screens and then mixed to a blend of stones and fines. It is widely used as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may be made from granite, line, dolostone, and other rocks. Also known as "crusher run", DGA (dense grade.
