Natural Gypsum: Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India. Applications: Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as: - a retarder for Portland cement - a fertilizer or soil conditioner - mineral filler - oxidizing agent in glass manufacture or other industrial applications. Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement. Imported Gypsum from Iran: Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.
Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly of silica. Nearly all particles are spherical in shape. Fly ash is a pozzolan, a siliceous material which in the presence of water will react with calcium hydroxide at ordinary temperatures to produce cementitious compounds. SiO2, Al2O3, Fe2O3 and occasionally CaO are the main chemical components present in fly ashes. Fly ash significantly improves concrete performance in different ways and also provides many benefits in cement and non-cement applications. Fly Ash colour can vary from grey and dark grey, yellowish tan and light to brownish. ADVANTAGES OF FLY ASH IN CONCRETE Fly Ash is a Pozzolan Improves concrete workability and lowers water demand Sulfate and Alkali Aggregate Resistancet Rise in compressive strength over time Environment friendly CEMENTATION Fly Ash is optimized for its fineness while reducing the water demand and improving the chemical compositions to maximise its benefits when used in concrete. Fly-ash can also be used as an add-on to concrete mixture with pozzolanic and/or latent hydraulic properties. We at CEMENTATION selectively collect fly ash and subject to rigorous testing, further refines these collected materials to produce quality fly ash products meeting the needs of our customers.

Silica sand is a primary component in the manufacturing of glass. It is a very important raw material for standard and special glasses. The chemical purity of silica sand is the principal determinant of strength, colour and clarity. It is used to produce flat glass for building and automotive uses and for container glass that stores food and beverages. It reinforces glass fibres and required for the production of fibreglass insulation. It is applied in speciality glasses that include test tubes, scientific tools, television and CRT monitors, and also in incandescent and fluorescent lamps. Calcium silicate bricks For manufacturing calcium silicate bricks, silica sand is mixed with high calcium lime with a sand to lime ratio of 10 or 20. These bricks contain good regularity, smooth faces, and sharp corners with a wide variety of strength. The durability of calcium silicate bricks is similar to concrete and is not resistant to sulphur containing environments. Silica sand for water filtration Silica sand is an effetive filtration bed in the removal of contaminants in both processing of wastewater and in the filtration of the drinking water. Silica sand neutralizes the acidic elements to maintain optimal pH balance in water filters. As it is chemically inert, it will not react when exposed to acids, contaminants, volatile organics or solvents. Metal Casting & Production Silica sand is an essential part of the production of steel, ferrous and nonferrous foundry industries for de-oxidation and grain refinement. For obtaining desired internal or external shapes, metal parts are cast in silica sand. It is a preferred choice for castings that involve cast iron, steel, titanium and also used to clean the casting surfaces. Paints & Coatings Silica sand constitutes of high-performance properties such as brightness, reflectance, oil absorption and colour-consistency. These properties help to improve the overall appearance and durability of industrial and architectural paints and coatings. Its low oil absorption nature improves finishing colour that makes a durable coating rich in pigments. Silica fillers improvement retention and also provide resistance to dirt, mildew, weathering and cracking
Egypt is one of the best places which you can find the Highest and purist Quality Silica-sand, CairoMinerals offer Quality Products with Competitive Prices since 2004 but we are not only in the market, you can find many companies in Egypt as well deal with white silica-sand What is silica sand ? Silica (SiO2) sand is generally the sand which you can get all over a beach and it also happens to be the most commonly used sand. It is most commonly composed by either crushing sandstone or else it is most commonly taken from natural occurring points or locations, such as beaches and river beds. The fusion point of purest form of silica is 1,760 �°C (3,200 �°F), however the sands which is used for extraction of silica exhibits a lower melting point due to impurities. For casting which requires high melting point, such as steels, at least 98% pure should be used; however for metals having lower melting points, like cast iron and non-ferrous metals, the sand have low purity can be used (between 94 and 98% pure). Silica-sand happens to be the most commonly used sand because it is found in abundance, and thus it costs low (therein being its greatest advantage). However there are some disadvantages of sand as well. The disadvantages of silica are high thermal expansion, which can result in casting defects in metals having high melting point, and low thermal conductivity, which can very easily result in defective casting. Apart from there that, there comes some more barriers with it. It also cannot be used in sync with some of the basic metals because it will chemically react with the metal, resulting in surface defects. Finally, it releases silica particles during the pour, risking silicosis in foundry workers. Silica Sand for Sale Commercial Silica-Sand is most commonly used as a means of proppant by companies which deals in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also utilized in industrial processing to manufacture regular use items such as glass, construction materials, personal care materials, electronics, and even renewable materials. Industrial sand happens to be a word which normally refers to silica-sand-products having extremely high purity with closely controlled sizing. It generally happens to be a clearer product than common concrete and asphalt gravels. The name Silica (SiO2) is provided to a handful of minerals solely made up of silicon and oxygen. Mostly it is found in the crystalline state. It is also found in an amorphous form which comes as a result of weathering or plankton fossilization Silica-sand deposits are generally mined and dig out in open pit processes. Extracted ore is subjected a lot of processing to enhance the silica content by reducing impurities. After that it is dried and sized to manufacture the best sized particle size distribution for the intended application.
