Fly Ash Used To Increase Strength Of Concrete CEMEX UK

Fly ash is the fine ash produced at coal-fired power plants that develops cementitious properties when mixed with cement and water. Widely used in the UK to increase the strength of concrete, fly ash is also used to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product.
