Jun 02, 2015· Concrete. Concrete is a heterogeneous mixture of cement, sand, crushed stone (or brick chips) and water. Aggregates like sand and stone are inert while cement and water undergo chemical changes and the mass hardens like artificial stone.
The current area of research in the concrete is introducing foundry sand in the ordinary concrete. Foundry sand is high quality silica sand with uniform physical characteristics. It is a byproduct of ferrous and nonferrous metal casting industries, where sand has been used for centuries as a molding material because of its thermal conductivity.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

“Concrete is a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregates, usually a combination of fine aggregates and coarse aggregates; in Portland-cement concrete, the binder is a mixture of a Portland-cement and water, with or without admixtures.”
Sharp Sand. Sharp Sand, also known as Concrete Sand is a coarse sand with larger particles. This type of sand is typically used in concrete. φ scale - 1 to 0 Size range - 1/2 to 1 mm (0.020–0.039 in) Builder's Sand. Builder's Sand, also known as Plasterer's, Mason, or Bricklayer's Sand is a finer grade sand with smaller particles.
These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks, and superhighways, houses and dams. The key to achieving a strong, durable concrete rests on the careful proportioning and mixing of the ingredients.
The desert sand from Maowusu sandy land is very fine aggregate. Currently, there are no national specifications concerning the application of desert sand with very fine grain. To apply the desert sand to concrete in civil engineering, concrete specimens made of the desert sand had been tested in order to clarify its engineering characteristics.

Properties of Concrete Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates. Properties of Concrete While cement in one form or another has been around for centuries, the type we use was invented in 1824 in Britain. It was named Portland cement because it looked like the
Foundry sand from casting industries is a waste material which is dumped extensively and in this study an attempt has been made to evaluate the usage of this waste material in concrete. The constant depletion of sand beds at all major sources of availability is a major concern and thus efforts are

The aesthetic properties of concrete blocks, once utilitarian and gray, have become more important. Concrete block manufacturers now produce concrete blocks in a wide range of colors, textures and finishes that architects utilize to great effect, depending on the building design.
Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
Abstract: The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. From the result of the sieve analysis, it shows that the sands used for the experiment is a well graded sand of zone 1 of BS882 parts 2 (1973).
