retarding action meaning in English
迟延动作
Examples
- The result shows , for this composite cement system , retarding action of dihydrate gypsum is more obvious than that of anhydrite , meanwhile , anhydrite tends to cause setting time short and water needed increased
结果表明：二水石膏对该种复合体系水泥的缓凝作用比硬石膏明显，硬石膏易引起复合体系水泥急凝和需水量增大。 - Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer , in which the overall amount of admixture is certain , this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar . the result shows that compatibilities of different components are different , and composition effects are also different
文摘:在总掺量一定的情况下，就萘磺酸盐高效减水剂与不同缓凝组分、缓凝型减水剂等复合后对水泥净浆流动度、缓凝作用、胶砂强度发展等性能的影响作用进行了试验分析，结果表明各不同组份复合的相容性不同，复合效应也存在差别。 - Hi this thesis , the setting time of various retarders had been tested , in which three retarders with good retarding action , citric acid , sodium tripolyphosphate , bone glue are respectively chosen from three types of retarders , hydroxyl carboxylic acid type , phosphate type and protein type , and the strength and setting time of gypsum added with them are determined . effect of some factors , such as ph value , fineness of hemihydrate , type of gypsum on the retarding action of the retarders is also studied
本文对多种缓凝剂进行凝结时间测试，选择效果良好的羟基羧酸、无机盐和蛋白质类型的三种缓凝剂：柠檬酸、多聚磷酸钠和骨胶，测定它们对石膏凝结时间、强度等宏观性能的影响，并分别研究ph值、石膏细度和石膏种类等因素对它们的缓凝效果的影响。
