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

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.
Bentonite as is a particular kind of clay derived from volcanic ash and consists mainly of montmorillonite with minor amount of illite, kaolinite, cristobalite and other minerals. Bentonite has strong colloidal properties and, when in contact with water, increases its volume several fold by swelling, forming a tixotropic, gelatinous substance. Main uses of Bentonite take advantage of these colloidal properties. The main characteristics of Bentonite is its decolorizing power, that is the property of the earth to absorb selectively certain pigments rather than others according to the characteristics of the product to be decolourized(acidity, oxidation degree, origin and biological state etc.)
APPLICATIONS
For Drilling Fluids
Pilling
Binder (e.g. foundry-sand bond, iron ore pelletizer)
Purifier
Electrical Earthing
Agriculture
Cosmetics, Paper, Paints and Ceramics
Absorbent (e.g. pet litter), and
As a Groundwater Barrier.
We CEMENTATION acquire own mines for Bentonite in India. We supply Bentonite for industrial, manufacturing, construction and drilling applications. Our production or supply capacity is more than 250,000 TPA.
At CEMENTATION a special attention is given while mining Bentonite as the materials physical and chemical properties are depended upon the interference of the other metal ions present in the soil.
Once the material sourced from mines are transferred to our factory and are left for drying in an open land to reduce moisture up to the desired level. After the drying process and other checks are done our skilled manpower will do a sorting of the material and then after the material goes to pulverizes for grinding to desired mesh size and are packed according to customers requirement. Our laboratories are well equipped to meet the needs of the diverse markets we serve.
Kaolin also called as China Clay is nearly white in colour. It is distinguished from other industrial clays based on its fine particle size and pure colourings. Its ability to disperse in water makes it an ideal pigment.
The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum silicate formed by the decomposition of minerals such as feldspar. Hydrous kaolin is characterized by its fine particle size, plate like or lamellar particle shape and chemical inertness.

Vermiculite is a hydrated magnesium aluminum sheet silicate mineral closely related to mica, and has all of the thermal and chemical resistance mica is known for. When subjected to heat, vermiculite expands and forms particles that are revered for being:
Lightweight
Incombustible
Compressible
Highly absorbent, soaking up to three times its volume in water
Non-reactive
Highly effective in cation exchange capacity
Vermiculite is found all over the world, including Australia, Brazil, Bulgaria, Kenya, Russia, South Africa, Uganda, USA and Zimbabwe. Specialty Vermiculite mines and processes vermiculite concentrate in facilities located in Encore, South Carolina. Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes.
The exfoliated vermiculite is also used in the construction industries today and has wide applications, one of them being used as an additive to fireproof wallboard. It is a lightweight aggregate for plaster, fire stop mortar and cementations spray fireproofing, proprietary concrete compounds, . It is also used as a component of the interior fill for fire stop pillows, along with graphite. It is a light weight isolative concrete and can also be used in ground swimming pools to provide a smooth pool base.
Calcite is the most widely available mineral found within our planetâ??s crust. It is the main component found in limestone and marble. It is also used as a building material, as an abrasive, as a construction aggregate and as a pigment. It is also used in agricultural soil treatment.
We source and manufacture our calcite mineral majorly from the regions of Rajasthan as it is the biggest source, followed by Andhra Pradesh and Madhya Pradesh.
The physical properties of calcite are softness with a value of 3 on the Mohs scale, high lustre, lower specific gravity and rhombohedral cleavage. Calcite differs from dolomite as its fragments effervesce readily in cold hydrochloric acid, whereas dolomite fragments do not.
Calcite is one of the most popular and functional minerals due to its ease in availability and strong functional properties. It is widely used in several industries such as paper, paint, ceramic, automobile, plastics, agriculture, glass, coal, construction, cosmetics and pharmaceuticals to name a few.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). It is a very common mineral, particularly as a component of limestone.
We use calcite as filler and coating material for quality paper packaging in the paper industry. It makes the paper surface hardened and smoothed. It also aids in the fast drying of the final paper product as it absorbs the oil rapidly. Further, in the paint and coating sector, our calcite mineral is used to replace pigment and protect steel from corrosion. It also provides improved water and chemical resistance.
In the ceramic industry, calcite increases the strength of ceramic products. It is added to the tile slurry during the tile manufacturing process to remove the negative effects of SiO2 in the medium. Furthermore, in the construction sector, calcite is used in the manufacturing of cement and concrete as limestone and marble.
In the coal mining sector, calcite is used to keep coal dust from exploding and spreading into flames. It also plays a significant role in hard water treatment. Calcite eliminates any hardness present in the water, cleans the water and controls the color of the water. In the leather industry, it is used in the pre-process of leather by aiding in removing the animal hair.
Our CMC products are suited for a wide range of applications since they are derivatives of a naturally occurring raw material and have high degree of purity. They are manufactured with cutting-edge technology and are subjected to rigorous quality control methods.
Due to its vast use in a variety of sectors, calcite is unquestionably the most popular and usable mineral. We manufacture calcite minerals using innovative technology and highly skilled manpower to ensure that all of our customers' end-product requirements get satisfied.
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed.
