water-reducing admixture meaning in Chinese
减水外加剂
普通减水剂
Examples
- This is generally accomplished by using water - reducing admixtures . specify air - entrained concrete for outdoor slabs subjected to freezing weather
也可以使用更高坍落度(的混凝土) ,但(制作混凝土的)混合物必须是设计用于制作不过量泌水和/或分离(混凝土)的(混合物) - Adding air - entrained agent can enhance the heat preservation performance of pumice concrete and improve its durability . using water - reducing admixture can improve the performance of pumice concrete , but the quantum is bigger than in the ordinary concrete
为获得良好的物理力学性能并提高混凝土的和易性，掺加减水剂对其性能改进具有明显的技术经济效果，其掺量要比普通混凝土稍高。 - Due to the fact that the study consequence about the influence of water - reducing admixture on the early - age shrinkge is scarce , this paper also broadly study influence of water - reducing admixture on the early - age shrinkge , drying shrinkage and whole shrinkge
研究结果证明，三类减水剂都增大了混凝土的早期收缩且增幅较大高达200 - 300 ，最终总收缩增幅达80 - 90 ，远远超过现行规范规定的收缩比。 - Eight concrete samples of different compound ratio of artificial lightweight aggregate ( coarse aggregate of expanded shale ) and ordinary aggregate , water - reducing admixture , expanding admixture , etc , are compounded firstly , based on the research of main properties such as agitating property , strength , dry surface density and deformation , an optimum compound ratio of the concrete with high strength ( cl40 ) , light density ( 1800 ) and slight expand is achieved
首先，采用人造轻骨料(页岩陶粒)及普通骨料，加入减水剂、膨胀剂等，配制出了八种不同配合比的轻骨料砼与普通砼，并对其和易性、强度、干表观密度、变形等主要性能进行了试验研究，得到了强度等级cl40 ，密度等级1800的轻骨料中高强度微膨胀砼最佳配合比。
