摘要：

Different　types　of　glycerophosphate　were　prepared,　and　the　impact　of　glycerophosphate　on　the　cement　hydration　process　was　investigated　by　X-ray　diffraction,　thermogravimetry　and　measurements　of　compressive　strength,　cement　paste　fluidity　and　heat　of　hydration,　respectively.　The　results　show　that　when　the　alcohol-acid　ratio　is　2,　glycerophosphate　has　a　positive　effect　on　the　promotion　of　the　cement　hydration　and　the　better　compatibility　with　polycarboxylate　superplasticizer　rather　than　triethanolamine.　Glycerophosphate　improves　the　amount　of　non-evaporable　water　and　reduces　the　amount　of　Ca(OH)2　in　hardened　cement　paste　via　the　promoted　hydration　of　slag　and　steel　slag.　©　2017,　Editorial　Department　of　Journal　of　the　Chinese　Ceramic　Society.　All　right　reserved.
