The Volcanic Ash Effect Of Slag

When slag powder is mixed into concrete, in the alkaline environment inside the concrete, the slag powder can have a "secondary hydration reaction" with the cement hydration product Ca (0H) 2, and can promote further hydration of cement to generate more C-S-H gel, so that the Ca (0H) 2 grains in the aggregate interface area become smaller, improve the microstructure of concrete, reduce the porosity of cement paste, and improve the cohesion of the aggregate interface, Greatly improve the physical and mechanical properties of concrete.
