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.

-White Charcoal, also known as Binchotan, is a type of hardwood charcoal that has traditionally been produced in Japan. It is called �¢??White�¢?? charcoal because of its light color and unique benefits that create economic value compared to traditional black charcoal. -Binchotan is the purest charcoal on earth by the highest carbon proportion (more than 92%) and is completely odorless, and smokeless when burning. White Charcoal is more difficult to ignite than black charcoal; however, it burns hotter and longer. When hitting the pieces together, it gives a light metallic sound. The white charcoal doesn�¢??t break into small pieces while burning. USAGES Food grilled over white charcoal retains its natural flavor and moisture because it burns cleanly and without flames. It is popular in high-end restaurants and mostly in Korea and Japan. In addition, binchotan has many uses such as water purification, exhaust filter, deodorant, skin care, metallurgy, used in battery manufacture...
