The hybrid effect of citric acid with polycarboxylate water-reducing agent (PCE) on the fluidity, setting time and mortar strength of high belite sulphoaluminate (HB-CSA) cement paste was investigated. The results show that citric acid with PCE prolongs the setting time of HB-CSA cement, but reduces the initial fluidity and early strength of the cement, and has no adverse effect on the later strength of the cement. The mechanism of citric acid with PCE to delay the early hydration of HB-CSA cement was analyzed by cement hydration microcalorimeter, X-ray diffractor and scanning electron microscope, and the adsorption behavior of citric acid with PCE in the early stage of hydration of HB-CSA cement was analyzed via organic carbon adsorption. It is indicated that the combined use of citric acid and PCE could delay the hydration heat release rate of the cement, inhibit the formation of ettringite, the early hydration product of cement, and change ettringite as a main hydration product of HB-CSA cement in the early stage. The morphology changes from rod-like or tubular to fine needle-like. The use of citric acid with PCE will produce a competitive adsorption in cement, thus reducing the effect of PCE dispersion in HB-CSA cement and cement fluidity.

研究了柠檬酸复合聚羧酸减水剂(PCE)对高贝利特硫铝酸盐(HB-CSA)水泥浆体的净浆流动度、凝结时间和胶砂强度的影响,发现柠檬酸复配PCE显著延长了HB-CSA水泥的凝结时间,降低了水泥的初始流动度和早期强度,对水泥后期强度无不良影响。通过水泥水化微量热仪、X射线衍射分析仪和扫描电子显微镜对两者复配延缓HB-CSA水泥早期水化的机理进行分析,并利用有机碳吸附仪分析柠檬酸和PCE在HB-CSA水泥水化早期的吸附行为。结果表明:柠檬酸与PCE复合使用显著延缓了该种水泥的水化放热速率,抑制了水泥早期水化产物钙矾石(AFt)的生成,改变了HB-CSA水泥早期主要水化产物AFt的形貌,使其由棒状、管状变为细针状。两者在HB-CSA水泥中会产生竞争吸附,因此柠檬酸会降低PCE在HB-CSA水泥中分散效果,使水泥流动度有所降低。

研究了柠檬酸复合聚羧酸减水剂(PCE)对高贝利特硫铝酸盐(HB-CSA)水泥浆体的净浆流动度、凝结时间和胶砂强度的影响,发现柠檬酸复配PCE显著延长了HB-CSA水泥的凝结时间,降低了水泥的初始流动度和早期强度,对水泥后期强度无不良影响。通过水泥水化微量热仪、X射线衍射分析仪和扫描电子显微镜对两者复配延缓HB-CSA水泥早期水化的机理进行分析,并利用有机碳吸附仪分析柠檬酸和PCE在HB-CSA水泥水化早期的吸附行为。结果表明:柠檬酸与PCE复合使用显著延缓了该种水泥的水化放热速率,抑制了水泥早期水化产物钙矾石(AFt)的生成,改变了HB-CSA水泥早期主要水化产物AFt的形貌,使其由棒状、管状变为细针状。两者在HB-CSA水泥中会产生竞争吸附,因此柠檬酸会降低PCE在HB-CSA水泥中分散效果,使水泥流动度有所降低。

The hybrid effect of citric acid with polycarboxylate water-reducing agent (PCE) on the fluidity, setting time and mortar strength of high belite sulphoaluminate (HB-CSA) cement paste was investigated. The results show that citric acid with PCE prolongs the setting time of HB-CSA cement, but reduces the initial fluidity and early strength of the cement, and has no adverse effect on the later strength of the cement. The mechanism of citric acid with PCE to delay the early hydration of HB-CSA cement was analyzed by cement hydration microcalorimeter, X-ray diffractor and scanning electron microscope, and the adsorption behavior of citric acid with PCE in the early stage of hydration of HB-CSA cement was analyzed via organic carbon adsorption. It is indicated that the combined use of citric acid and PCE could delay the hydration heat release rate of the cement, inhibit the formation of ettringite, the early hydration product of cement, and change ettringite as a main hydration product of HB-CSA cement in the early stage. The morphology changes from rod-like or tubular to fine needle-like. The use of citric acid with PCE will produce a competitive adsorption in cement, thus reducing the effect of PCE dispersion in HB-CSA cement and cement fluidity.
