摘要：
This work unravels for the first time the concentration dependent retarding effect of borax on tri-magnesium phosphate-based cements by studying the hydration and the phases formed in the set cements, exploiting multiple characterization techniques. In the presence of borax, the hydration was found to be slower and less exothermic, leading to the formation of struvite without newberyite, with no effect on cement's strength. The observed boron species allowed us to ascribe the retardation to the complexation of NH4+ and Mg2+ by borate and polyborate anions.
