摘要
通过试验,对掺不同品种减水剂的水工混凝土基本力学性能、热学、自身体积变形、抗冲击韧性、抗冲磨强度、抗裂性能进行了研究。结果表明,与JM-PCA减水剂相比,掺减缩型JM-PCA(IV)减水剂的强度、极限拉伸值、抗冲磨强度、抗冲击韧性、平板抗裂性均有所下降;掺X404减水剂的强度、抗冲磨强度、抗冲击韧性、平板抗裂性均有所提高。
Through experiments, the basic mechanical properties, thermal, self-volume deformation, impact toughness, abrasion resis- tance and crack resistance of hydraulic concrete with different kinds of water reducing admixtures were studied.The results showed that JM-PCA （IV） water-reducing admixture has a decrease in strength,ultimate tensile strength, abrasion resistance, impact toughness and slab crack resistance compared with JM-PCA water reducing agent.The strength, abrasion resistance, impact toughness and crack resistance of X404 water reducing agent are all improved.
