(Elsevier, 2019-07-11)
Alkali-activated concretes have been receiving increasingly attention as they are identified to be key components towards achieving sustainable construction in future. A detailed comparative environmental assessment study ...
Environmental and economic perspective of waste-derived activators on alkali-activated mortars
(Elsevier, 2020-10-14)
Alkali-activated binders have been considered a low carbon alternative to cement and are produced by reacting aluminosilicate precursor with an alkali-activator. However, alkali-activators have been observed to be a major ...
