Admixture In Cement

Advantages of using mineral admixture in cement

Fly ash

-Improves strength and durability of concrete

-Increased resistance towards chemical attacks

-Better workabilit

Blast furnace slag

-Improved durability

Increased setting time

-Strength gain continues for a long period of time

-Reduced risk of damages by alkali – silica reaction

-Resistant to chloride and sulphate attacks

Silica fumes

-Better compressive strength and resistance to abrasion

-Reduced permeability of chloride ions

-Improved workability

-Reduces bleeding

Rise husky ash

-Heat of hydration of concrete is reduced

-Permeability of concrete is reduced

-Improved resistance to chloride and sulphate attacks

Metakaolin

-Increased compressive & flexural strengths

-Reduced permeability

-More resistant to chemical attacks

-Durability is increased
