One-part slag-mullite geopolymer: role of solid activators on connected porosity and mechanical properties (opens in new tab)

Geopolymer cements with reliable mechanical and durability properties could be a promising environmentally-friendly alternative to Portland cement. Connected porosity (CP) and compressive strength (CS) are critical parameters governing the durability of slag–mullite geopolymers. This study examines the relationship between connected porosity and mechanical performance in one-part slag–mullite geopolymer mortars activated by various solid alkaline salts, including sodium- and potassium-based a...
