摘　　要：研制成功了性能优良、价格低廉的新型碱矿渣水泥，在大量试验基础上确定了该水泥的最佳配方，水泥标号达到４２５＃及５２５＃。耐化学腐蚀试验表明新型碱矿渣水泥具有比普通硅酸盐水泥更优的抗化学侵蚀性；扫描电镜矿相形貌显微分析、Ｘ射线衍射分析和差热分析，展示新型碱矿渣水泥的主要水化产物为低碱度的水化硅酸钙、钙矾石和杆沸石型的水化硅铝酸钙钠，正是这三种主要水化产物的恰当配合，赋予了新型碱矿渣水泥高的强度和优异的耐久性。文章最后指出了新型碱矿渣水泥的开发和应用前景。In this paper,the authors develop successfully a new alkali-activated slag cement(NASC) with excellent performances and cheap price,and the optimun composition of this cement with grade reaching 425#and 525# has been determined on the basis of a large number of tests.Test results on resistance to chemical attack indicate that NASC possesses more excellent anti-chemical attacking property than that of Ordinary Portland Cement.SEM、XRD and DTA show the main hydration products of NASC are low-alkali hydrous calcium silicate、Ettringite and calcium sodium silico-aluminate hydrate similar to Thomsonite,their appropriate coordination endows with high strength and excellent durability to NASC.Finally the prospects of development and application of NASChave been pointed out.
