Fly ash is an inexpensive replacement for portland cement used in concrete, while it actually improves strength, segregation, and ease of pumping of the concrete. Fly ash is also used as an ingredient in brick, block, paving, and structural fills. Fly ash can be a cost effective partial substitute for Portland cement in markets that are experiencing supply shortages.
An industrial by-product that is otherwise waste, fly ash is environmentally friendly because it is recycled and has low embodied energy.
Because fly ash cement requires less water than portland cement, it is easier to use in cold weather. It can be formulated to produce various set times, cold weather resistances, strengths and strength gains, depending on the job. Fly ash can be used sparingly as an admixture or in large amounts to replace portland cement. The material is somewhat lighter than portland cement.
