中文摘要：

选取聚羧酸高效减水剂15.5%,亚硝酸钠3%,十二烷基苯硫酸钠0.02%,硫酸铁0.025%进行复配试验,制备新型的生态混凝土外加剂ZS-3;同时进行生态混凝土性能试验,掺这种外加剂的混凝土的强度不但达到了市场要求,浆体内的pH值更是降到8左右,为植物的生长提供了良好的条件,有利于生态。还分别从宏观和微观两方面研究了这种生态外加剂的性能。

英文摘要：

Inordertoproductaneweco-concreteadmixturewhich wascalled ZS-3,It selected 15.5% ofpolycarboxylatesuperplasticizer,3% of sodium nitrite,0.02% of dodecyl benzene sodium sulfate,and 0.025% of ferric sulfate for experiments of mixtures;simultaneously proceed ecological concrete performance test,the result showed that the strength of the concrete which added this admixture not only meet the market requirements,but only the pH of the slurry body was reduced to as far as to 8,the situation provided good conditions for the growth of plants and was beneficial to ecological.It also studied the property of the ecological admixture from macroscopic and microcosmic.
