Jul 08, 2021 Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.

Coal ash can potentially be utilized as partial replacement for cement in concrete and mortar formulations. The use of coal ash can lessen the cost and energy production, and reduce the impact on the environment. At present, the annual coal ash generation amounts to 2.78 Mt and may reach to 13.02 Mt by 2035 in the Philippines.
The Philippines is largely a coal consuming country with coal having the highest contribution to the power generation mix at 44.5 in 2015. But, local demand for coal is not limited to power generation. In 2015, the cement industry utilized 15.22 of the countrys coal supply, 5 went to other industries such as alcohol, sinter, rubber boots ...
Jan 12, 2017 Unlike other coal-fired power plants, Ang said San Miguel throws away no waste byproducts since everything is used as raw material for cement production. The ash resulting from the burning of coal is pozzolanic in nature and, as such, is also used as a cement production additive. We throw away nothing here that can pollute the environment ...
