摘要: 以电石渣、脱硫石膏、粉煤灰等工业废渣为原料,并添加氟化钙、二氧化钛、氧化铜等不同种类和掺量的矿化剂,制备以硅酸二钙和硫铝酸钙为主要矿物的多孔胶凝材料;运用X射线衍射技术,通过K值法对硫铝酸钙含量进行定量分析,探讨不同矿化剂的掺入对硫铝酸钙矿物形成的影响。实验结果表明:矿化剂的加入能够降低硫铝酸钙的形成温度,同时能促进硫铝酸钙的形成。氟化钙掺量为1%(质量分数)时硫铝酸钙的含量最高,为12.43%(质量分数);当氟化钙掺量超过1%时硫铝酸钙含量下降。二氧化钛掺量为0.5%(质量分数)时硫铝酸钙含量最高,达17.85%(质量分数);当二氧化钛掺量超过1.5%时硫铝酸钙含量下降较为明显。氧化铜适宜的掺量为0.5%~1.0%(质量分数),掺量超过1.5%时硫铝酸钙含量显著下降。

Abstract: Porous cementing material,with dicalcium silicate and calcium sulphoaluminate as the main minerals was prepared by adding different kinds and amounts of mineralizers,such as  calcium fluoride,titanium oxide,and copper oxide,with some industrial waste residues like fly-ash,carbide slag,desulfurization gypsum,and so on as the raw materials.Calcium sulphoaluminate content was analyzed quantitatively with K value method by XRD technology,and the effect of different mineralizers on the formation of calcium sulphoaluminate was investigated.Experiment results showed that the addition of mineralizer could decrease the formation temperature of calcium sulphoaluminate and promote its formation.For calcium fluoride, when its doping amount reached 1%(mass fraction,same blew),the content of calcium sulphoaluminate was the highest, reached 12.43%,and when its amount exceeded 1%,calcium sulphoaluminate content began to decline.For titanium dioxide, when it doping amount reached 0.5%,the content of calcium sulphoaluminate was the highest,reached 17.85%,and when the its amount exceeded 1.5%,the content of calcium sulphoaluminate reduced obviously.For copper oxide,the optimum doping amount was at 0.5%~1.0%,when its amount was more than 1.5%,the content of calcium sulphoaluminate reduced obviously.
