摘要
采用Ca(NO_3)_2和Na_2SiO_3合成了CSH凝胶。通过详尽的XRD分析,证实了CSH凝胶的层状结构,其层间距为11.6～14.2A;并以DSC和非蒸发水量的实验结果加以证实。对其中水的作用也进行了研究,实验结果有助于建立完整的水泥石结构模型。
CSH gel has been synthesised by the use of Ca(NO_3), and Na_2SiO_3. It is Proved that CSH gel has layer structure with basal spacing of 11. 6～14. 2A°using detailod XRD analysis. This conclu- sion has also been proved by the result of DSC ana1ysis and unevaporation water. The study on wa- ter in CSH gel has been done too. The results can help us to establish a complete structure modle of Hardend Cement Paste.
