摘要
本研究选取净水胶比、水泥用量和陶粒粒径作为关键参数,通过正交试验,研究其对透水陶粒混凝土的表观密度、连续孔隙率、透水系数和抗压强度的影响。研究结果表明:抗压强度随水泥用量增加而增大;水泥用量和陶粒粒径是主要影响因素;最优配比方案确定为净水胶比0.30,水泥用量200 kg/m^(3),陶粒粒径16~20 mm。
Utilizing an orthogonal experimental,the effects of net water-binder ratio,cement content,and the size of porous ceramic aggregate on the apparent density,continuous porosity,permeability,and compressive strength of pervious ceramisite concrete were studied.The results show a positive correlation between cement content and compressive strength.Cement content and the size of porous ceramic aggregate have a significant impact on the performance of pervious ceramisite concrete.The optimal combination is the net water-binder ratio of 0.30,cement content of 200 kg/m~3,and the use of porous ceramic aggregate with a size range of 16~20 mm.
