High-alite sulphoaluminate cement clinker and preparation method and application thereof
The high-alite sulphoaluminate cement is energy-saving cement which is high in early strength, has micro-expansion and erosion resistance, can be constructed in winter and is stable in strength increase, and is characterized in that the clinker comprises the following components in percentage by weight: 5-20% of SiO2, 10-20% of Al2O3, 1-10% of Fe2O3, 30-60% of CaO and 2-13% of SO3. The saturationratio coefficient of clinker lime is 0.90 +/-0.05; the aluminum rate is 4.5 +/-0.5; the silicon rate is 2.0 +/-0.5, and the sulfur-aluminum ratio is 1.2 +/-0.1. The invention is characterized in thatthe sulphoaluminate cement clinker containing high-content tricalcium silicate can be sintered at 1,250-1,350 DEG C while the burdening scheme is adopted, and the amount of tricalcium silicate in thesulphoaluminate cement clinker sintered within the temperature range is basically zero.
一种高阿利特硫铝酸盐水泥是一种早期强度高、具有微膨胀、抗侵蚀性，且可在冬季施工，强度稳定增长的节能型水泥，其特征在于以重量百分比计，所述熟料中SiO25‑20％，Al2O310‑20％，Fe2O31‑10％，CaO 30‑60％，SO32‑13％。熟料石灰饱和比系数：0.90±0.05；铝率：4.5±0.5；硅率：2.0±0.5，硫铝比：1.2±0.1。本发明的特点在于采用上述配料方案的同时，可在1250‑1350℃下烧成含高含量硅酸三钙的硫铝酸盐水泥熟料，而一般在这个温度范围内烧制的硫铝酸盐水泥熟料中硅酸三钙的量基本为零。
