| 摘 要： | 本文研究了新型干法水泥窑中含大量K_2O的旁路窑灰和粉煤灰制成的蒸养制品的强度和微观结构,以及掺少量硅灰对制品强度和微观结构的改善作用。结果表明,制品中存在过多的K_2O时,会改变水化硅酸钙的形貌、增大孔隙率和最可几孔径,使制品的抗压强度下降。掺少量硅灰可以抑制K_2O的不利影响,提高制品的抗压强度。

| Abstract: | In this paper, the effect of K_2O in the cement kiln dust on the macro properties and microstructure of steam cured fly ash-cement kiln dust products was studied. The beneficial effect of adding a small amount of silica fume on the properties and structure of the products with high K_2O content was also studied.The results show that if extra alkali content exists in the product, it will change the morphology of C-S-H gel, increse porosity in the product and decrease its compressive strength. By adding a small amount of silica fume to the product with high alkali content, the harmful effect of K_2O can be reduced and the compressive strength of the products can be improved. |
