摘要
研究了掺入石粉后的水泥基和外加剂的适应性。通过检测水泥净浆流动度和不同粉体的吸附量进一步解释不同岩性、不同细度的粉体对外加剂的适应性情况。结果表明外加剂的掺量极大的影响外加剂吸附量的大小。在一定范围内吸附量值随着外加剂掺量增加而增加。粉体对外加剂的吸附量随着粉体细度的增加先增大后减小,存在转折点。同时石粉的岩性对外加剂的吸附量也有一定的影响。
This paper studies the stone powder incorporated into the cement and admixture adaptability. It explained that powders of different fineness and admixture adaptability case by detecting the degree of fluidity of cement paste and the amount of adsorption of different powders. The results show that admixture content greatly affect admixture adsorption size.Adsorption values will increase when a certain range of additives content increases.Powder will absorb admixtures, which presents first increase adsorption and then decrease with the increase of powder fineness. Meanwhile stone powder lithology also has some impact on the adsorption admixture.
