Some Issues of Shrinkage-Reducing Admixtures Application in Alkali-Activated Slag Systems
Significant drying shrinkage is one of the main limitations for the wider utilization of alkali-activated slag (AAS). Few previous works revealed that it is possible to reduce AAS drying shrinkage by the use of shrinkage-reducing ...
Effect of Na3PO4 on the Hydration Process of Alkali-Activated Blast Furnace Slag
In recent years, the utilization of different non-traditional cements and composites has been increasing. Alkali-activated cementitious materials, especially those based on the alkali activation of blast furnace slag, have ...
Cement Kiln By-Pass Dust: An Effective Alkaline Activator for Pozzolanic Materials
Cement kiln by-pass dust (CKD) is a fine-grained by-product of Portland clinker manufacturing. Its chemical composition is not suitable for returning back into feedstock and, therefore, it has to be discharged. Such an ...
Influence of alkali ions on the efficiency of shrinkage reduction by polypropylene glycol in alkali activated systems
(ICE Publishing, 2018-06-01)
Alkali-activated materials, especially when activated by water glass, exhibit substantial drying shrinkage that hinders their broader industrial application. The effect of shrinkage-reducing admixtures (SRA), based on ...
