使用时，由破碎机1对废弃混泥土进行破碎研磨，制成粉末后由称量斗2 称量，之后通过传送装置3进入后续的混合搅拌器4内与Na2SiO3激发剂进行混合搅拌，制成水泥混合材料，在混凝土制作过程中作为掺和剂使用，可以减少混凝土原料的使用，且在适当的掺和比例下制成的混凝土与普通混凝土无较大区别。When in use, the waste concrete is crushed and ground by the crusher 1, weighed by the weighing hopper 2 after being made into powder, and then mixed and stirred with the Na 2 SiO 3 activator in the subsequent mixing agitator 4 through the conveying device 3 , made of cement mixture, used as an admixture in the concrete production process, can reduce the use of concrete raw materials, and the concrete made under the appropriate mixing ratio is not much different from ordinary concrete.
