CSH凝胶结构的探讨

针对ＣＳＨ凝胶中的孔结构特点进行了研究。利用各种测试方法的不同特点来研究各种不同干燥条件ＣＳＨ凝胶的孔形态。这些测试方法包括：ＳＡＸＳ法、压汞法、氮气吸附法、有机溶剂吸附法等。对ＳＡＸＳ方法进行了较详细的研究，结果表明：用ＡＳＡＸＳ方法来研究ＣＳＨ凝胶的孔结构确定是一种很有效的实验手段，并对引进基体相电子密度起伏的可能原因进行了探讨。

STUDY ON PORE STRUCTURE OF CSH GEL

In this paper,pore structure and characteristic of CSH gel are studied.The author emphasizes that a lot of measuring methods that have different characteristics should be used to study pore morphology of CSH gel in different drying conditions.The measuring methods include SAXS,nitrogen adsorption,mercury intrusion,organic solvent adsorption.SAXS method is studied in detail.It is indicated that SAXS method is really an effective means in study pore structure of CSH gel.The author also discusses the possible causes leading to electronic density deviation of matrix.
