Structure, morphology and compressive strength of Alkali-activated mortars containing waste bottle glass nanoparticles

Alkali-activated materials (AAMs) have emerged as a sustainable, clinker free binder alternative to portland cement, with reduced consumption of raw materials and very low CO2 emissions. They are produced via the activation of aluminosilicates with alkaline solutions. Millions of tons of bottle glas...
