The Characteristic Study on the Raw Chemical Gypsum and Slag Cementing System

摘要：

A simple method that used untreated chemical gypsum, quicklime and slag to produce a kind of gupsum compound cementious material is introduced in this paper,the material was analysed by X-ray diffraction (XRD), mecury intrusion pressure instrument(MIP). The results showed the mechanical property produced by cast molding method was good, the main hydration products of the material were ettringite and C-S-H gel, the strength of the press molding specimen was low and the pore structure determined by MIP showed the much-detrimental pores took a great volume ratio in the total pore volume.

关键词： gypsum compound cementious material mechanical property hydration products pore structure.
