Paste filling cementing material for tailings containing Zn and PAM as well as preparation method and application of paste filling cementing material
According to the paste filling cementing material for the tailings containing Zn and PAM and the preparation method and application of the paste filling cementing material, the delay effect of Zn and PAM in the tailings on hydration of a cement-based cementing material is reduced, normal hydration and condensation of the cementing material are guaranteed, then the early hardening strength of paste filling slurry is improved, and the service life of the paste filling slurry is prolonged. And the use amount of a cementing material for achieving the same filling and hardening effect is reduced in a disguised manner.
本发明提供了一种用于含Zn和PAM尾砂的膏体充填胶凝材料及其制备方法与应用，该膏体充填胶凝材料降低了尾砂中Zn和PAM对水泥基胶凝材料水化的延缓作用，保证了胶凝材料的正常水化和凝结，进而提高了膏体充填料浆的早期硬化强度，变相减少了达到相同充填硬化效果时的胶凝材料用量。
