High-iron aluminate cement
The invention discloses high-iron aluminate cement, which is obtained by calcining bauxite in a decomposition furnace outside a kiln; high-calcium stone and desulfurized gypsum are also added into the calcined bauxite raw material; according to the weight fraction, the bauxite accounts for 35-37 parts, the high-calcium stone accounts for 47-49 parts, and the desulfurized gypsum accounts for 15-17 parts. The high-iron aluminate cement disclosed by the invention has the beneficial effects that the problems that when the aluminum content in bauxite is relatively low, the prepared high-iron aluminate cement is short in setting time, low in strength and relatively poor in corrosion resistance by adopting a traditional calcining process and a raw material ratio are solved.
本发明公开了名称一种高铁铝酸盐水泥,采用窑外分解炉煅烧铝矾土得到;煅烧铝矾土原料中还添加有高钙石和脱硫石膏;按照重量分数,铝矾土为35‑37份、高钙石为47‑49份、脱硫石膏为15‑17份。本发明的有益效果是:解决了当铝矾土中铝含量较低时,采用传统的煅烧工艺和原料配比,制得的高铁铝酸盐水泥存在着凝结时间短,强度低,抗腐蚀性能较差的问题。
