Fly ash is the fine ash produced at coalfired 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.
In this study, the effect of nano silica (NS) on the properties of cement pastes incorporated with of fly ash cenospheres (FACs) has been investigated. A fixed amount of 1 % NS was added to cement pastes containing various proportions of FAC. It was found that NS was beneficial in improving the mechanical strength of the FAC modified cement pastes.

Mar 28, 2019· Fly ash cement is a primary ingredient in certain concretes that is often used as an alternative to Portland cement, which is a more traditional concrete base. The ash itself is a byproduct of coal combustion, but once formed into a cement the ash usually binds in such a way as to neutralize many of the chemicals and toxins that have made coal burning so controversial in recent years.
