Crack Self-Healing in Alkali-Activated Materials: From Mechanisms to Strategies for Enhancing the Healing Efficiency
… is calling for sustainable construction materials since portland cement production contributes about 8% of global anthropogenic carbon dioxide emissions. Alkali-activated materials (AAMs) have emerged as promising alternative binders to curb carbon dioxide emissions from portland cement …

Characterisation and properties of alkali activated pozzolanic materials.
Many of the waste materials produced from modem heavy industries are pozzalans, which develop cementitious properties when finely divided in the presence of free lime. This property allows a potential industrial use for this waste as a cement replacement material in concrete. An example of such a …

Sustainable cementitious materials for building and sorption applications
… applications. Two sustainable cementitious materials that are frequently researched as an alternative to OPC are calcium sulfoaluminate (CSA) cement and alkali-activated materials (AAMs). CSA cement lowers CO<sub>2</sub> emission by over 40% compared to OPC, and it is advantageous due to …

Effect of carbonation on bound chlorides in cementitious and alkali activated binders
… contributes to 4% of the global CO2 emission. Alkali activation of aluminosilicate industry by-products, such as ground granulated blast furnace slag, fly ash or calcined clays, can provide a viable binder system that can contribute towards the cement market. Activators such as sodium hydroxide …

Reactivity of crystalline slag phases in cementitious systems
… concretes with different chemistries, e.g. alkali-activated materials, blended Portland cements, and calcium sulfo-aluminate cements. This thesis focuses on improving our understanding of how the constituent phases of steel and copper slags interact with the aqueous phase of concrete, with …

Prospective retarders for alkali-activated slag: stability at high alkalinity, effects on setting behavior and strength of paste
… of ordinary Portland cements. Geopolymers or alkali-activated systems with precursors as fly ash, slag or metakaolin, or a mixture of these, are possible substitutes. There are several hindrances to their use in construction due to the lack of understanding and control of properties of the …
