阿利特-硫铝酸盐水泥熟料的气固反应制备及水化性能
|
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SO_2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·3Al_2O_3·CaSO_4(C_4A_3$)矿物,实现3CaO·SiO_2(C_3S)和C_4A_3$的共存。在SO_2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C_3S含量52.61%和C_4A_3$含量2.13%共存的阿利特-硫铝酸盐体系水泥熟料。阿利特-硫铝酸盐体系水泥由于C_4A_3$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。
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 SO_2 and temperature on phase composition of clinker,hydration performance and structure of the cement.Results showed that 3CaO·3Al_2O_3·CaSO_4( C_4A_3$) could be introduced into Portland cement clinker to realize the coexistence of C_4A_3$ and alite.52.61% 3CaO·SiO_2( C_3S) coexisted with2.13% C_4A_3$ in alite-ye'elimite clinker could be obtained with 40 mL/min SO_2 gas flow at 1 250 ℃ for30 min.As the existence of C_4A_3$,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.
