控制铁相组成生产用于道路的普通硅酸盐水泥

【摘要】 硅酸盐水泥熟料的铁相，是C2F－C6AF2－C4AF－C6A2F连续固溶体。一般煅烧条件下，其铁相主要为C4AF。引入一定量的含矿化离子的工业废渣配料，可以增加Al2O3在钱相中的固溶量，从而可得到以C4AF－C6A2F为主的铁相，其摩尔比大作为Cao：Al2O3：Fe2O3=5：1．5：1。这种熟料及其磨制的普通硅酸盐水泥，具有良好的耐磨性及很小的子缩率。在云南省高等级公路路面试用，效果良好。更多还原

【Abstract】 The iron phase of Portland cement clinker is a member of continuous solid solution between C2F-C6AF2-C4AF-C6A2F.Under normal burning conditions, the iron phase is mainly C4AF, When certain amount of ndneralizing ion bearing industrial slag isadded, the Al2O3 solved in the iron phase solid solution can be increased, hom which the iron phase ohtained will be henly contaireing GAF - C6A2F.The mol ratio is generally Cao: Al2O3: Fe2O3 = 5: 1. 5:1. The oulinap Portland cement made from thiskind of clinker has good abrasive resistance with little shrinkage. It is already used for highway consmiction in Yunnan province andearned good reputation.更多还原
