How environmentally sustainable are fibre reinforced alkali-activated concretes?
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 Assessment of Alkali-Activated Mortars Using Different Activators
(CISA Publisher, 2019-10)
This study sheds light on the environmental performance of three alkali-activated mortars (AAMs) using sodium hydroxide, sodium silicate powder and 2-part aqueous alkali solutions respectively, as activators. A comparative ...
Recycling mica and carbonate-rich mine tailings in alkali-activated composites: A synergy with metakaolin
The main objective of this paper was to investigate the alkali activation of mine tailings (MT) after mechanochemical activation and the effect of metakaolin (MK) addition. Finnish mica-rich tailings from a phosphate mine ...
Environmental and economic perspective of waste-derived activators on alkali-activated mortars
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 ...
