8 REASONS TO USE FLY ASH AS AN ADMIXTURE IN CONCRETE

Effects of fly ash on concrete properties

Admixtures are substances which when added to concrete in small doses can overcome some of the drawbacks viz., poor workability, high shrinkage cracks, poor performance against chemicals, high permeability, inadequate protection of steel reinforcement from corrosion, low tensile strength and lower fracture toughness. Admixtures can be defined as materials other than water, cement and aggregate, … Read more
