Thermochemistry study of the effect of alkali content on the early geopolymerisation at room temperature

Zhang, Z. and Yao, X. and Wang, H. (2010) Thermochemistry study of the effect of alkali content on the early geopolymerisation at room temperature. In: 1st International Conference on Advances in Chemically-Activated Materials (CAM 2010), 9-12 May 2010, Jinan, China.

Abstract

Chemically activated materials usually consist of potentially cementitious components and chemical activator(s). The cementitious components include granulated blast furnace slag, granulated phosphorus slag, steel slag, coal fly ash, volcanic glasses, zeolite, metakaolin, silica fume and non-ferrous slags. Caustic alkalis, alkaline salts and calcium chloride are the most common activators. During the past two decades, alkali-activated cements and concretes have attracted strong interests all over the world due to their advantages of low energy cost, high strength and good durability compared to Portland cements. A major incentive for further development of such cements is generated by low CO2 emission and generation of vast amounts of industrial by-products such as coal fly ash, steel slag, non-ferrous slags, etc. Applications for chemically activated materials are being increasingly explored and tried because of its many advantages over conventional Portland cement.
