范文编号:CL130 范文字数:21711,页数:42 普通混凝土高效减水剂的研究 本文通过对国内外普通混凝土高效减水剂近况的研究,选取、制备了不同配合比的普通混凝土试块,并测定了所制备的混凝土试块的强度性能指标。通过选择最佳的物料配比、以及不同的减水剂用量,建立起混凝土试块强度与减水剂之间的对应关系曲线。研究表明:不同减水剂用量对混凝土试块抗压强度的影响是不同的,随减水剂用量的增加,抗压强度有先增强后减弱的趋势,效果不明显,但比不加减水剂的强度有明显提升 。
This text adopts the research which is the recent developments of ordinary concrete high-efficient water-reducing agent by domestic and international’s study , choosing preparing the ordinary concrete lump of different match ratio, determining the intensity performance index of the concrete lump prepared, choosing the strongest as well the best match and studying impacts on compression strength of the concrete lump by different water-reducing agent consumption . Studies have suggested: Change according to the impact on concrete lump compression strength of consumption of different water-reducing agent, with the increase of consumption, the weaken trend that compression strength has strikingly to strengthen effect not obvious, obviously promote than without auxiliary intensity. Key words: Ordinary concrete Water reducer Compression strength
