Original Abstract

In recent years, the use of various non-traditional cements and composites has increased. Alkali-activated materials, especially those based on alkali activation of blast-furnace slag, have considerable potential in construction industry. However, alkali-activated slag binders exhibit significant shrinkage, in some circumstances several times greater than portland cement-based materials, which hinders wider use of these materials in numerous applications. Therefore, the use of specific admixtures suitable for alkali-activated systems is necessary. This paper is consequently focused on testing the efficiency of shrinkage-reducing additives based on polypropylene glycols, as well as their influence on the hydration mechanism and mechanical properties of prepared alkali-activated materials.
