Fly Ash Dealers in Gurugram

We can supplyexport bellow mentioned fly ash for cement manufacturing or bricks manufacturing only in fob delivery terms. Class f fly ash the burning of harder, older anthracite and bituminous coal typically produces class f fly ash. This fly ash is pozzolanic in nature, and contains less than 7% lime (cao). Possessing pozzolanic properties, the glassy silica and alumina of class f fly ash requires a cementing agent, such as portland cement, quicklime, or hydrated lime—mixed with water to react and produce cementitious compounds. Alternatively, adding a chemical activator such as sodium silicate (water glass) to a class f ash can form a geopolymer. Class c fly ash fly ash produced from the burning of younger lignite or sub-bituminous coal, in addition to having pozzolanic properties, also has some self-cementing properties. In the presence of water, class c fly ash hardens and gets stronger over time. Class c fly ash generally contains more than 20% lime (cao). Unlike class f, self-cementing class c fly ash does not require an activator. Alkali and sulfate (so 4) contents are generally higher in class c fly ashes. At least one us manufacturer has announced a fly ash brick containing up to 50% class c fly ash. Testing shows the bricks meet or exceed the performance standards listed in astm c 216 for conventional clay brick. It is also within the allowable shrinkage limits for concrete brick in astm c 55, standard specification for concrete building brick. It is estimated that the production method used in fly ash bricks will reduce the embodied energy of masonry construction by up to 90%.[9] bricks and pavers were expected to be available in commercial quantities before the end of 2009.[10
