Original Abstract

Plasticizers and superplasticizers has been the one of the most important improvement in concrete technology during the last century. The effect of different types of plasticizing admixtures was widely studied in the ordinary Portland cement (OPC) systems, but much less in the case of the alkali activated systems. The aim of this work is to clarify the efficiency of lignosulfonate based plasticizer and polycarboxylate-based superplasticizer on the behaviour of alkali activated blast furnace slag. The workability, mechanical properties as well as hydration mechanism with different kind of admixtures had been determined. Subsequently, the stability affecting the efficiency of the plasticizing admixtures in a high alkaline environment has been studied using X-ray photoelectron spectroscopy (XPS) to investigate the chemical changes in the structure of plasticizing additives.
