摘要
本文通过水泥材性、熟料岩相鉴定、XRD、TEM、水化热以及孔结构等多方面的试验研究论证了C_(11)A_7·CaF_2-C_2S体系熟料的矿物组成以及该水泥在硬石膏掺与下,从水化5分钟开始到3个月所形成的水化产物和水化速度。同时也阐明了这一体系水泥具有凝结硬化快、小时强度高以及长期强度增长和稳定性好的缘由。
A series of experiments were carried out by means of chemical analysis, petrographic analysis, XRD, TEM, determination of heat of hydration and pore size distribution. This paper reports in details the mineral composition of the clinker of C_(11)A_7·CaF_2-C_2S system and the hydration rate and products formed after 5 minutes to 3 months of hydration. The paper also explains why this kind of cement possesses such faverable properties as quick setting and rapid hardening, high 'hour' strength, and steady development of long term strength.
