蒸养粉煤灰砌块生产中,胶结料由粉煤灰,生石灰和石膏三者组成。石膏的掺加量虽然不大,却能显著地改善粉煤灰硅酸盐的一系列品质指标。显然,控制适宜的石膏配比对于提高砌块质量具有重要意义。石膏的作用以及石膏用量对蒸养粉煤灰硅酸盐性能的影响,概括起来:在制品蒸养之前,石膏延缓了生石灰的消解速度,保证物料在成型过程中有足够的流动度,有利于
In the production of steamed fly ash blocks, the binder is composed of fly ash, quicklime and gypsum. Although the addition of gypsum is not large, it can significantly improve a series of quality indicators of fly ash silicate. Obviously, controlling the appropriate ratio of gypsum is of great significance for improving the quality of the block. The effects of gypsum and the amount of gypsum on the performance of steamed fly ash silicates are summarized: Before the products are steamed, the gypsum retards the speed of quicklime digestion and ensures that the material has sufficient flow during the molding process, which is beneficial to
