【摘要】 添加适量激发剂可以缩短氟石膏胶凝材料凝结时间,较大幅度提高氟石膏水化率,加快氟石膏水化进程。SEM分析结果表明,激发剂可以改变氟石膏硬化体晶体形貌。在激发剂的作用下,氟石膏硬化体中有较多发育完全,以棒状、柱状为主的CaSO4.2H2O和CaSO4.1/2H2O生成。更多还原

【Abstract】 The appropriate amount activators could reduce the setting time of fluorogypsum cementitious materials and enhance the hydration rate and the hydration process of fluorogypsum to gypsum considerably.The SEM micrograph analysis results showed that the activators could change the microscopic morphology of the hardened cementitious materials formed by fluorogypsum hydration.The crystalline particles had more fully developed,with rod and columnar grain consisting mainly of CaSO4·2H2O and CaSO4·1/2H2O.更多还原
