Environmental and economic perspective of waste-derived activators on alkali-activated mortars
Abdulkareem, Mariam; Havukainen, Jouni; Nuortila-Jokinen, Jutta; Horttanainen, Mika (Elsevier, 14.10.2020)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 ... -
Environmental Assessment of Alkali-Activated Mortars Using Different Activators
Abdulkareem, Mariam; Havukainen, Jouni; Horttanainen, Mika (CISA Publisher, 10 / 2019)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 ... -
How environmentally sustainable are fibre reinforced alkali-activated concretes?
Abdulkareem, Mariam; Havukainen, Jouni; Horttanainen, Mika (Elsevier, 11.07.2019)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 ... -
