摘要:
采用气固反应法制备了阿利特-硫铝酸盐体系水泥熟料。利用X线衍射仪(XRD)、水化量热仪、压汞法(MIP)等技术分析了SO2气体流量和煅烧温度对水泥熟料矿物组成的影响,以及该体系的水化性能和浆体结构。结果表明:硅酸盐水泥熟料中可引入3CaO·3Al2O3·CaSO4(C4A3$)矿物,实现3CaO·SiO2(C3S)和C4A3$的共存。在SO2流量为40 mL/min、温度为1 250 ℃条件下处理硅酸盐水泥熟料30 min可制备C3S含量52.61%和C4A3$含量2.13%共存的阿利特-硫铝酸盐体系水泥熟料。阿利特-硫铝酸盐体系水泥由于C4A3$的存在,凝结时间和水化诱导期较硅酸盐水泥短,早期的孔隙率和早期强度均优于硅酸盐水泥。
Abstract:
Method of gas-solid reaction was selected to prepare alite-ye’elimite cement clinker.X-ray diffraction(XRD),isothermal calorimetry and mercury intrusion porosimetry(MIP)were used to study the influence of SO2 and temperature on phase composition of clinker,hydration performance and structure of the cement.Results showed that 3CaO·3Al2O3·CaSO4(C4A3$)could be introduced into Portland cement clinker to realize the coexistence of C4A3$ and alite. 52.61% 3CaO·SiO2(C3S)coexisted with 2.13% C4A3$ in alite-ye’elimite clinker could be obtained with 40 mL/min SO2 gas flow at 1 250 ℃ for 30 min. As the existence of C4A3$,the induction period of hydration and setting time for alite-ye’elimite cement was shorter than that for Portland cement,and the total porosity and the strength of alite-ye’elimite cementim proved greatly compared with Portland cement at the early age.
