Original Abstract

Nowadays alkali activated binders are one of alternative materials to Portland cement. Alkaline activation is a process when the material hardens in medium at pH > 12. This paper presents the study of stability of different polymer admixtures (polypropylene glycol, polyvinyl alcohol, polyethylene glycol with different molecular weight, different modifications of commercial polymer admixtures VINNAPAS® and shrinkage-reducing Peramin SRA) in alkaline media at pH = 12.42. The influence of the alkaline medium on the properties of polymer admixtures was examined by infrared spectroscopy. All types of VINNAPAS®, Peramin SRA are unstable in high alkaline media.
