Effect of fly ash to slag ratio and Na2O content on leaching behaviour of fly Ash/Slag based alkali activated materials

, 2023
Alkali–activated materials (AAMs) with variable levels of activator and precursor loading were evaluated for their long–term leaching behaviour. On a series of fly ash (FA)/slag–based binder mixes containing varying amounts of slag (0 – 30 wt%) and Na2O (

Experimental study on flexural mechanical properties of steel fiber reinforced alkali-activated slag concrete beams

Frontiers in Physics
As an environmentally friendly alternative to ordinary concrete, slag concrete is subject to limitations such as drying shrinkage and micro-cracking during its promotion and application. In order to address these challenges, steel fibers, known for their

Microstructure and porosity evolution of alkali activated slag at various heating temperatures

Journal of Materials Research and Technology, 2020
This paper elucidated the microstructural and porosity evolution of alkali activated slag at 800 °C up to 1200 °C. The microstructural analysis obtained shows the changes in surface densification of glassy phase and nucleation of dynamical grains within ...

Thermal Properties of Alkali Activated Slag Plaster for Wooden Structures [PDF]

Scientific Reports, 2020
AbstractCurrently, the production of green building materials grows up. Alkali-activated materials (AAMs) based plaster have better fire resistance properties compared to Portland cement-based concrete and plasters. Compared to Portland cement-based systems AAMs retain a significant level of structural stability after exposure to fire events. AAM based
