| 摘 要： | 外加剂作为混凝土的第五组分,在新型混凝土的发展过程中扮演着越来越重要的角色。其中,减水剂的应用最为广泛。结合混凝土减水剂的应用现状,主要选取萘系、脂肪族和聚羧酸三种减水剂,进行对比研究。研究表明:运用优选法得出三种减水剂的最优掺量和最优掺量区间分别是萘系:1.208%,(1.174%,1.264%);脂肪族:0.637%,(0.630%,0.649%);聚羧酸:0.265%,(0.248%,0.292%)。通过线性回归建立数学模型,使每种减水剂的掺量与标准立方体抗压强度关系线性化,具有一定实用价值。

| Abstract: | As the fifth component of concrete,the admixtures play an increasingly important role.Among them,the water-reducing agent is most widely used.Combining the current situation of development of the concrete water-reducing agent,we mainly select three representative efficient water-reducing agents,to do comparative study of optimization method.The results not only find out the optimal dosages and the optimal intervals of three water-reducing agents,but also set up the mathematical model for how to select the o... |
