Comprehensive utilization method of coal gangue
The invention relates to the technical field of coal gangue recycling, in particular to a coal gangue comprehensive utilization method which comprises the following steps: re-sorting coal gangue by using a vibration exciter to obtain coal gangue coarse aggregate and coal gangue fine aggregate; mixing cement, lime, an additive and fly ash into the mixed aggregate of the coal gangue coarse aggregate and the coal gangue fine aggregate, and intensively stirring by using stirring equipment to obtain a mixture; adding mixing water into the mixture, and stirring to obtain coal gangue concrete; the shock excitation treatment and the autoclaving treatment improve the bonding force of cement particle groups so as to ensure that water enters the particle groups and is subjected to hydration reaction with the smallest cement particles with the highest bonding force. On the other hand, enterprise cost can be reduced and income can be increased by reducing the addition amount of cement, and huge economic benefits are brought to application enterprises.
本发明涉及煤矸石回收利用技术领域，尤其涉及一种煤矸石综合利用方法，包括利用激振器对煤矸石进行再分选，得到煤矸石粗集料和煤矸石细集料；在煤矸石粗集料和煤矸石细集料的混合集料中，掺入水泥、石灰、添加剂以及粉煤灰，并利用搅拌设备进行集中搅拌，制得混合料；向混合料中添加拌合水，搅拌制得煤矸石混凝土；所述激振处理以及压蒸处理提高水泥颗粒团的粘接力，以保证水进入颗粒团内部与最细小、最具有粘合力的水泥颗粒发生水化反应，本发明一方面可以打打提高公路的抗压能力，另一方面可以通过降低水泥添加量来实现降低企业成本增加收入，给应用企业带来巨大的经济效益。
