Effect Of Fly Ash On Concrete Strength. Strength development and hydration characteristics of concrete mixtures with significant amounts of fly ash are relevant research topics. In recent studies many researchers found that the use of. It is claimed that the permeability of fly ash was lower compared with the permeability of controlled concrete after 28 days of curing. Research results indicate that ash with high carbon content reduces the workability of mixtures thus increasing the water demand and thereby reducing the strength of the concrete.
But the entirely submerged concrete is less affected by the above factor. Fly Ash effect on concrete exposed to seawater The concrete used in marine has a danger of wetting and dying waves abrasion by debris and sand freezing and thawing cycles and reinforcement corrosion which are occurred in a chemical medium. By means of fly ash in concrete in place of cement reduces the consumption of natural resources diminishes the environmental pollution and also economical as replacing the cement which is costlier by the fly ash. Fly ash concrete strength development is mainly affected by the degree and way fly as influence the workability. It is claimed that the permeability of fly ash was lower compared with the permeability of controlled concrete after 28 days of curing. The article Mix Design for Optimal Strength Development of Fly Ash Concrete Cement and Concrete Research 1989 Vol.

In recent studies many researchers found that the use of. Research results indicate that ash with high carbon content reduces the workability of mixtures thus increasing the water demand and thereby reducing the strength of the concrete. It was also observed that up to 30 replacement of PPC by fly ash strength is almost equal to referral concrete after 56 d.

An enormous amount of fly ash is generated in thermal power plants in India which affects the environment and living organism.
