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.

Alkali-activated cements and concretes have been used for many applications in China. However, there are still no official standards and specifications for the testing and evaluation of the properties of this type of materials in many countries. This is the first international conference held in China in the field of chemically activated materials. More than a dozen of experts from Europe, Australia and Canada were invited to present on different topics of chemically activated materials. A total of 39 papers from 15 countries were received and 29 of them are selected in this proceedings. It is hoped that this conference will promote exchange of the most recent information, development of test methods and specifications and lead to increased acceptance and use of chemically activated materials.
