摘要
主要从化学方法出发,研究了Na2SiO3溶液改性、盐酸改性和水煮改性对再生混凝土微粉的改性效果,并从亲水系数、德国矿粉值、亚甲蓝值以及表观相对密度这4个方面进行对比,结果表明使用盐酸改性再生混凝土微粉的方案是最优的。
Three methods of chemical modifications were investigated in this paper,including Na2SiO3 solution modification,hydrochloric acid modification and water-boiling modification.According to the performances of hydrophilic coefficient,German filler value,methylene blue adsorption value and apparent relative density of those three methods,we got the conclusion that the hydrochloric acid modification is the best way to modify the recycled concrete powder.
