Abstract

Although it is one of main cement phases, the reactivity of tetracalcium aluminoferrite (C4AF) has not been fully understood especially under the use of grinding agent. In this study, the crystallographic variations due to the use of diethanol isopropanolamine (DEIPA) and resulting hydration characteristics of iron-rich C4A0.6F1.4 (f-C4AF) and idealized C4A0.8F1.2 (i-C4AF) were investigated. Substantially enhanced reactivity of f-C4AF was confirmed due to the state variation of Fe atom in C4AF from Fe2+ to Fe3+ which facilitates the formation of Fe-bearing phases of C3FH6, Fe-AFm and FH3. Meanwhile, the degree of hydration of i-C4AF had not been substantially improved but showed similar reaction only with a large amount of DEIPA (from 0.1% to 0.3%). It was experimentally validated that the reactivity of C4AF is controllable with the use of DEIPA which can lead to develop sustainable cement such as ferrite rich Portland cement.

期刊介绍： The Journal of Sustainable Cement-Based Materials aims to publish theoretical and applied researches on materials, products and structures that incorporate cement. The journal is a forum for discussion of research on manufacture, hydration and performance of cement-based materials; novel experimental techniques; the latest analytical and modelling methods; the examination and the diagnosis of real cement and concrete structures; and the potential for improved cement-based materials. The journal welcomes original research papers, major reviews, rapid communications and selected conference papers. The Journal of Sustainable Cement-Based Materials covers a wide range of topics within its subject category, including but are not limited to: • raw materials and manufacture of cement • mixing, rheology and hydration • admixtures • structural characteristics and performance of cement-based materials • characterisation techniques and modeling • use of fibre in cement based-materials • degradation and repair of cement-based materials • novel testing techniques and applications • waste management
