Effect of a Combination Fly Ash and Shrinkage-Reducing Additives on the Properties of Alkali-Activated Slag-Based Mortars
Original language description
This study is aimed at reducing the drying shrinkage of alkali-activated slag (AAS) through the use of low-calcium fly ash (FA) and commercially available shrinkage-reducing additives (SRAs) originally developed for OPC-based binders, since there are no such admixtures tailored for AAS systems. Generally, all the SRAs tested are based on modified alcohols. All the mortars were based on slag activated by waterglass, with the water-to-slag ratio equal to 0.40 and the sand-to-binder ratio 2:1. In the first step, the effect of the partial replacement of slag by FA (25, 50 and 75) % of mass fractions on the drying shrinkage and compressive strength was investigated. On the basis of the obtained results a mortar with 50 % FA in the binder was chosen for subsequent experiments, where the influence of three types of SRAs on the drying-shrinkage behaviour was examined.
