WebIn this work, the effect of introducing fly ash in the concrete mixture at a dosage of 30% by cement weight, replacing either cement or fine aggregate,on the corrosion behaviour of … WebKeywords: fly ash; corrosion; durability 1. Introduction Its relatively low cost and high compressive resistance and molding capability make concrete a frequently used construction material worldwide [1]. However, several agents that are found in the environment degrade cement and concrete. WebWith higher ash usage ratios, the permeability of concrete is reduced which gives concrete structures protection against freeze/thaw deterioration and the penetration of chemicals and salts into the structures that cause corrosion and premature failure. cindy keith
