摘要
本文介绍了一种高钙膨胀熟料的生产技术。主要原材料是石灰石和铁粉,其中石灰石Ca O≥53%,铁粉Fe2O3≥65%。主要矿物成分为f Ca O】75%,含少量C3S、C4AF,但是不含C3A。熟料的烧成温度为1400℃~1420℃。高钙膨胀熟料可用于生产混凝土膨胀剂,辅助原料是硫铝酸盐熟料和硬石膏。
This paper introduces a kind of production technology about high calcium clinker. Main raw material is limestone and iron powder, limestone Ca O content is 53% or higher, iron powder Fe2O3 content is 65% or higher. The main mineral composition for f Ca O content is more than 75%, containing a small amount of C3 S and C4 AF, but excluding C3 A. Clinker sintering temperature is between 1400 ℃ and 1420 ℃. High calcium clinker can be used in the production of concrete expansive agent, auxiliary materials are sulphoaluminate clinker and anhydrite.
