摘要
通过大量的实验 ,研究了几种有机外加剂对水泥砂浆、混凝土的凝结时间、塌落度及负温下强度的影响。实验结果表明醇类和羧酸盐类物质混合掺入混凝土中 ,提高了砼的塌落度和负温下的强度 ,防止了无机盐类对混凝土耐久性不良的影响 。
With plenty of tests,the paper study on the influence of several organic admixture upon cement mortar,concrete set time,collapsed slump and the strength in negative temperature In result the concrete mixed with alcoholate and carboxylic acid can improve the collapsed slump and the strength in negative temperature,prevent the bad influence of inorganic salt on concrete endurance,that provide the experimental fund for using organic pumping antifreeze agent
