| 摘 要： | 研究了Ca(OH)_2、硬石膏及少量可溶性钙盐(甲酸钙、乙酸钙等)复合对高炉矿渣活性的激发作用及物料配比与性能的关系。结果表明:Ca(OH)_2与硬石膏复合对矿渣活性有一定的激发效果,可溶性钙盐的加入降低了水泥的pH值,进一步激发了矿渣的活性,乙酸钙(Ca(CH_2COOH)_2)的激发效果好于甲酸钙(Ca(COOH)_2);在矿渣掺量为80%,Ca(OH)_2掺量15%,硬石膏掺量5%,外加1.0%Ca(CH_2COOH)_2生产出的无熟料水泥28 d抗压强度达54.6 MPa;Ca(COOH)_2与硬石膏促进高炉矿渣水化的主要水化产物为钙矾石和C-S-H凝胶。

| Abstract: | The activating effect of blast furnace slag under the activation of Ca(OH)_2,CaSO_4,and some soluble calcium salts(calcium formate,calcium acetate) was investigated,as well as the relation between material proportion and property.The results show that Ca(OH)_2 combined with CaSO_4 increases the activity of slag significantly.The lowing of pH caused by the addition of soluble calcium can further stimulate the activeness of slag.Comparably,the effect of Ca(CH_2COOH)_2 is better than Ca(COOH)_2 to stimulate th... |
