Strength and microstructure of alkali-activated phosphorous slag binder: Effects of activator type/dosage and phosphorous slag chemical composition

In this paper, the influence of sodium hydroxide and water glass of various modulus, as activators, on the compressive strength, microstructure and hydration products of two alkali-activated phosphorous slag (AAPS) with different chemical composition were studied. Water glass activation shows relatively higher later compressive strength when the...
