Washed sand is surface mined, screened and washed to remove silt and clay, then allowed to drain. It is typically a light buff color, almost off-white.
Washed sand is finely graded sand and can be used for fill to top dress golf course greens, and as a base for laying brick and pavers
Washing sand removes all silt and settlement from the sand. It also removes excess salt that can harm plants.
The range of Wash Sand, that we supplying is after very effective Water Treatment solution for removing concrete, epoxy paints, rust, mill scale rust and paint from the steel surfaces. It is shaped specifically to suit its applications and is carefully washed, dried, and screened.
A dune is a hill of sand built by either wind or water flow. Dunes occur in different shapes and sizes formed by interaction with the flow of air or water. Most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter "slip face" in the lee of the wind.
In most cases, the dunes are important in protecting the land against potential ravages by storm waves from the sea.
Dune sand has a number of uses. The size, uniformity, chemical purity and nature of dune sand make it a singular resource. It is an excellent filter for removing sediment and bacteria from water.
The sand is used to make molds and cores. The molds are used to form metal into a variety of shapes. Core sand fills the spaces where metal is not needed or wanted. Sand is used in sandblasting silica sand.
Backfill is mainly natural material that is used to fill in some void left after construction or excavation efforts. Usually, the backfilling is a combination of stone, soil and other materials that were left over after the main portion of the project was completed. However, the backfill may be transported to the building site if necessary.
It is also common to backfill the area immediately around the foundation of a building. Using the compacted earth and stone that was excavated in order to create a smooth site for the construction of the building, the backfilling is piled against the finished foundation. The result is that water will tend to flow away from the foundation and help minimize the chances of the rapid deterioration that would lead to weakening the entire structure.
Limestone is a sedimentary rock, formed by inorganic remains, such as shells or skeletons that have compressed for a very long time. The main element found in limestone is calcium carbonate magnesium, iron or manganese as well, which affect the whiteness and hardness. Limestone is one of the major ingredients used in construction materials
Limestone is used in virtually all construction materials. It is added in with clay and heated to form cement, which can be made into mortar by adding sand and water. Mortar is used to set bricks and act as an adhesive when it dries. Limestone is also used in concrete and asphalt filler.
Limestone is used in making steel products. It is added to mix with impurities in the melted iron, producing slag. The slag is separated from the iron leaving it clean of all impurities and limestone, which is then made into steel.
Limestone is used in a wide range of plastic and elastomeric, or rubber, products. The regular and controlled shape of the limestone particles and size of these particles makes it a great filler material for the production of plastic and rubber. Fillers are used to expand expensive plastics or other materials to increase the product size without the cost. Since limestone is a non-reactive material, it is perfect for this application.
Limestone can be added to water to remove impurities and pollutants. Since limestone is primarily made of calcium carbonate, a base substance, it can be used to neutralize acidity in industrial waste and run-off. Limestone can also be used to reduce soil acidity for agriculture.
Limestone can be used in pigment-making and as filler for more expensive paints. Paper is also manufactured using limestone. Wood is treated with acid to help break it down, which is then treated with limestone to neutralize the acid and whiten paper. Limestone is also used in dyes and carpeting or other floor coverings, such as protective resins and coatings.
This is a layer of gravel without a lot fines on top of the subgrade. A base course on top of the sub base makes it easier to get to the proper grade and to get it flat. If you use some sort of a choker course of finer material on the top of the sub base, it will support your people and equipment during concrete placement. It will also keep your slab thickness uniform, which will save money on concrete—the most expensive part of the system. And a flat base course will allow the slab to slide easily as it shrinks, reducing restraint and the risk of cracks as the concrete contracts after placement (drying shrinkage).
Limestone powder is the most widely used building material in the world. This status is the result of the good physical and chemical qualities of limestone. Lime is stone; therefore it does not decompose, shrink or expand. Limestone powder and smaller crushed soil recommended to be used as construction materials, especially for road construction.
Gabbro is dense material of coarse-grained rocks that consists of primarily of plagioclase feldspar and pyroxene.
Gabbro aggregate used concrete is highest compressive and flexural tensile strength and abrasion resistance than other aggregate used concrete. Highly qualified Chartered Certified Engineers are always recommending using gabbro aggregates for the concrete where high compressive strength required for piles, columns and walls.
Gabbro can be used as ornamental facing stones, paving stones and it is also known by the trade name of 'black granite. It is also used in kitchens and their countertops under the misnomer of 'black granite'.

The following materials were observed and estimated as part of the construction waste component:
Waste materials that are predominately new wood from new construction. This may include plywood, chipwood, dimensional lumber (2x4's, etc.) shavings and sawdust.
Gypsum wallboard that is a waste product from new construction.
Inert materials such as brick, concrete, rock, and dirt that originated at a construction site. This masonry material was "c1eaner" and "newer" than the demolition masonry materials.
Metallic materials that were a waste product of new construction. This material consisted of new metal studs and metal beams and pipes
Metallic materials that were a waste product of new construction. This material consisted of new metal studs and metal beams and pipes Plastic waste materials used in new construction. This included PVC plumbing pipe, PVC siding, Styrofoam insulation, and plastic sheet.
