Fly ash is used: In the production of lightweight concrete. Low-cement concrete is used in the preparation of road bases. Fly ash is also used in slag-silicate concretes, which are used to repair roads, airfields, bridges, as well as in the construction of acid-resistant floors in chemical plants, livestock farms, and metallurgical facilities. In the production of foam concrete, its introduction into the foam concrete mixture increases the aggregate stability of the mixture between the beginning and end of the cement dough setting, which prevents the movement of components and prevents negative effects on the formation of the structure. Fly ash easily replaces cement in the production of mortars, ready-mixed concrete, and finished products. It is used as an additive to cement without reducing its activity, is used in the preparation of concrete for road construction, and as an additive to clay in the manufacture of tiles and bricks. As a component of dry construction mixes: production of dry masonry mixes consisting of cement, sand, fly ash, ICP, and powdered superplasticizer.
Aluminum stock A7 - is primary technical purity aluminum, molded into bars of non-regulated dimensions. The basic chemical composition of aluminum A7 includes: iron - up to 0.16%, silicon - up to 0.15%, titanium - up to 0.01%, manganese - 0.03%, copper - up to 0.01%, zinc - up to 0.04%, and of course aluminum - 99.7% (impurities not more than 0.02%!). Stock A7 is a raw material for the production of alloys with the presence of aluminum.

Rice husk ash is used in the production of special high-quality steel with low thermal conductivity and density. ZRSH is added to the heat-insulating mixture to cover the mirror of the metallurgical ladle, which additionally ensures compliance with the temperature regime of continuous casting processes. Ash is used as a filler in polymers and rubbers for the production of car tires, as an adsorbent for heavy metals for wastewater treatment. In the pharmaceutical industry, ash is added to stabilize emulsions, as an agent, thickener and suspending gel in the preparation of semi-solid products, in perfumery, RHA is added as a filler for toothpastes and creams.
Equally important is the use of rice husk ash as a natural source of high performance amorphous silica.

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.
Fly ash, also known as flue-ash is a residue which is generated during combustion and consists of fine particles. There are impurities in coal which mostly consist of clays, limestone and dolomite particles. These turn up into ash as they cannot be completely burned.
Fly ash is useful in a number of ways and is one of the most researched upon mineral source. It is mainly a pozzolanic substance which contains aluminum and silicon material which in return due to the presence of water can take form of cement.
A lot of research and development initiative have been taken place across the globe to build and develop technologies that can utilize the full potential of fly ash. Royal Mineral takes care to ensure flawless production stages.
