Shrinkage mechanisms of alkali-activated slag
Spletpred toliko dnevi: 2 · The mechanism of action of the alkali-activated slag with limestone powder (AAS-LS) composite system is still unclear. (2) Currently, most of the research and evaluation on the chloride ion transport properties of alkali-activated materials have been done in laboratory environment. Splet07. apr. 2024 · Three alkali-activated binders were produced with 30% portland cement and different types of ash (70% of bottom ash, 70% of rice husk ash, or 35% of each type of ash). Chemical shrinkage was measured by the buoyancy method.
