Composite Portland cement and preparation method and application thereof
The invention discloses composite Portland cement as well as a preparation method and application thereof. The preparation method of the composite Portland cement comprises the following steps: adding water into the additive for dispersion, then spraying the additive into the nano filler, then adding the low-activity solid waste powder, uniformly mixing, then drying, then adding into a ball mill together with the Portland cement, and then carrying out ball milling to obtain the composite Portland cement. Under the condition that a large amount of low-activity solid waste is added, the water demand, the setting time and the mechanical property of the composite Portland cement are not affected, recycling and treatment of the low-activity solid waste can be well achieved, and the composite Portland cement is suitable for large-scale application and popularization.
本发明公开了一种复合硅酸盐水泥及其制备方法和应用。本发明的复合硅酸盐水泥的制备方法包括以下步骤：将外加剂加水分散，再喷洒到纳米填料中，再加入低活性的固体废弃物粉料后混合均匀，再进行干燥后与硅酸盐水泥一起加入球磨机，再进行球磨，即得复合硅酸盐水泥。本发明的复合硅酸盐水泥在大量添加低活性的固体废弃物的情况下，其需水量、凝结时间和力学性能却并未受到影响，可以很好地实现低活性的固体废弃物的再利用和处理处置，适合进行大规模推广应用。
