中文摘要：

试验选用三乙醇胺、二乙烯三胺,三异丙醇胺,氨基乙基乙醇胺,聚乙烯醇磷酸铵作为早强剂,研究其在微小掺量下对硅酸盐水泥标准稠度用水量、凝结时间、与外加剂的适应性、胶砂强度等方面的影响。试验结果表明,醇胺类化合物的掺加对水泥标准稠度用水量产生了增大的趋势;三乙醇胺与N-（2-羟乙基）乙二胺明显的缩短了水泥的初凝时间与终凝时间,三异丙醇胺、二乙烯三胺延长了水泥的初凝时间,缩短了水泥的终凝时间;三异丙醇胺与N-（2-羟乙基）乙二胺在0.2‰掺量时对水泥的流动度无影响,N-（2-羟乙基）乙二胺在0.1‰掺量时,使水泥的流动度得到增加,其它组均对水泥与外加剂的适应性造成不良影响;除了三异丙醇胺在掺量为0.20‰与0.50‰时的早期强度低于空白水泥之外,其他各组都有不同程度的增加,后期强度,三异丙醇胺在任何掺量下,明显强于三乙醇胺。

英文摘要：

This subject mainly chooses triethanolamine, diethylenetriamine, Triisopropanolamine, aminoethyl ethanolamine polyvinyl alcohol ammonium phosphate as early strength agent, study the influence of them in a small content on Portland cement standard consistency water, setting time, and the adaptability of the admixtures, mortar strength etc. Test results show that, mixing aleohol amine compounds on the standard consisteney water produce an increasing trend. Triethanolamine and N-（2- bydroxylethyl） etbylenecliamine significantly shorten the initial setting time and final setting time of cement and triisopropanolamine, diethylenetriamine extend the initial setting time of cement and shorten final setting time of cement. Triisopropanolamine and N - （ 2 - hydroxyethyl） ethylenediamine in 0.2%v dosage have no effect on the flow of cement, but N - （ 2- hydroxyethyl） ethylenediamine in dosage of 0. 1‰, increases the flow of cement. Other groups have an adverse impact on the adaptability of the cement and admixture. In addition to the early strengths of triisopropanolamine content in 0.20‰ and 0.50‰ dosage is lower than theblank cement, other groups have increased in varying degrees. As to later intensity, triisopropanolamine in any content is significantly stronger than triethanolamine.
