【摘要】 三乙醇胺作为一种激发剂,通常认为能提高水泥土的早期强度。在实验室内进行的三乙醇胺对水泥土强度影响的试验研究表明,三乙醇胺的激发作用与土质有明显关系,三乙醇胺并非对所有的土有早强和增强作用,有些土中掺加三乙醇胺会导致水泥土早期强度明显下降;在使用三乙醇胺作为激发剂时,必须进行实验室室内试验,以确定其有效性。更多还原

【Abstract】 As an excitant,triethanolamine was considered can improve the early stage strength of cement stabilized soil.By experiment,we found that the priming action of triethanolamine is close connection with the ingredients of soil;triethanolamine is not always increase the strength of cement stabilized soil.In some kind of soils,adding triethanolamine will decline the early stage strength of cement stabilized soil.When using triethanolamine as an excitant,it is necessary that do experiment to test the effect of triethanolamine.For maintain the representative of result,it is necessary that using the fresh soil to do experiment.更多还原
