Sand provides bulk, strength, and other properties to construction materials like asphalt and concrete. It is also used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a moulding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper.
Construction sand and gravel, one of the most accessible natural resources and a major basic raw material, is used mostly by the construction industry. Despite the low unit value of its basic products, the construction sand and gravel industry is a major contributor to and an indicator of the economic well-being of the Nation.
What Stone Dust Is. Stone dust is like a darker, coarser version of sand. It is a byproduct of running stones through a crushing machine to make crushed stone. Its exact composition will obviously depend on what kind of stone was run through the machine. For instance, sometimes granite is run through such a machine; in other cases,
In the world of construction, concrete like other materials is playing an important role in development. concrete is a composite material which is a mixture of cement, fine aggregate, coarse aggregate and water .The major constituents of which is natural aggregate such as gravel, sand, Alternatively, artificial aggregates such manufactured sand furnace slag, fly ash, expanded clay, broken bricks and steel

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Uses of Aggregate. Aggregate can be used in a number of ways in construction.
Some of the more important properties of aggregates for granular base and subbase include: Gradation – a wide range of aggregate sizes and gradations are used depending on the pavement type and the conditions to which the granular base and subbase will be subjected.

advantages disadvantages of using crusher dust instead of sand in r.c.c work.. Answer / salim mansuri there is basic property (physical and chemical) difference in cement, and crusher dust, so it does not bind each other properly and therefore there may create hair like creack, hence the durebility of the concrete and building structure
Properties of Aggregates and its Values for use in Construction Home / How To Guide / Properties of Aggregates and its Values for use in Construction Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article.
Sand crusher is mainly applied to all kinds of stone crushing operations, and is divided into many types according to the differences in crushing theory and particle size. Sand crusher is widely used in mining, smelting, building material, highway, railway, water conservancy, chemical
Weblog about construction aggregate: crushed stone and sand. The physical properties of aggregates stem from the inherent properties of the source rock; these include texture, structure, and mineral composition. Textural properties give rise to internal characteristics,
The Closed Circuit Cone Crusher is one of the main equipments for artificial sand production. Its finished sand has a uniform plasmid and high compressive strength. Compared with natural sand, it is more in line with the requirements of high standard construction sand, and the machine is working.

Feb 04, 2015The recent findings have also indicated that varying the properties (flakiness) of coarser crushed sand fractions (0.125/2 mm and 2/4 mm) has much less relative impact on fresh concrete properties, and that the other fine particle (≤ 0.125 mm) characteristics, such as shape, surface texture and mineralogy, could have a similar effect as grading (specific surface).
Aggregate. The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product. Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ashes (clinkers), burned shale, and burned clay.
