Ambient Temperature Drying Shrinkage and Cracking in Metakaolin-Based Geopolymers
Extensive cracking of geopolymers upon drying is a well known problem. First paper to report a systematic investigation of drying with new conclusion that some water forms part of the geopolymer structure, whereas accepted view was that water was only a reaction medium. The work allows putting bounds on the relative humidity and temperature conditions which will give rise to disintegration of these construction materials. Led to an invited lecture at the first UK workshop on geopolymers (KTN Materials, 4/12/2013) and the setting up of a student exchange with Dr Hashimoto (shinobuh@nitech.ac.jp) of the Nagoya Institute of Technology, Japan.
