摘要/Abstract

摘要： 本文采用不同掺量的磷建筑石膏(CPG)、粒化高炉矿渣和熟石灰制备超硫酸盐水泥(SSC),通过测试水泥浆体的水化热、电阻率、化学收缩、水化产物、孔溶液pH值和抗压强度的变化规律,研究了CPG掺量对SSC水化性能的影响规律。结果表明:当CPG掺量从0%(质量分数,下同)增大到20% 时,水泥浆体的第三放热峰出现时间延迟,3 d放热量与14 d化学收缩均增大,3 d电阻率减小,28 d孔溶液pH值从11.95减小到10.80;掺入CPG会促进钙矾石的生成;当CPG掺量为10%时,试件的28 d抗压强度最大,达到23.8 MPa。

Abstract: The supersulfated cement (SSC) with different content of calcined phosphogypsum (CPG), ground granulated blast-furnace slag and slaked lime was prepared in this study. The effect of CPG content on the hydration properties of SSC was investigated by testing the variation of hydration heat, electrical resistivity, chemical shrinkage, hydration products, pore solution pH value, and compressive strength of cement slurry. The results show that the third peak of heat release curves of cement slurry delays when the CPG content increases from 0% (mass fraction, the same below) to 20% . The cumulative heat at 3 d and the chemical shrinkage at 14 d increase with the increase of CPG. However, the electrical resistivity at 3 d decreases with the increase of CPG, and the pore solution pH value decreases from 11.95 to 10.80. The incorporation of CPG promotes the formation of ettringite. When CPG content is 10%, the 28 d compressive strength of specimen reaches the maximum of 23.8 MPa.

Key words: supersulfated cement, calcined phosphogypsum, ground granulated blast-furnace slag, hydration heat, electrical resistivity, chemical shrinkage
