Regenerated UHPC cement concrete and preparation method thereof
The invention discloses regenerated UHPC cement concrete and a preparation method thereof, and belongs to the field of building materials. The concrete comprises the following components in parts by weight: 100 parts of recycled UHPC cement, 35-40 parts of water, 180-220 parts of fine aggregate, 280-350 parts of coarse aggregate and 0.5-0.8 part of a water reducing agent. The regenerated UHPC cement concrete is prepared by crushing, screening, grinding and chemically exciting and stirring waste UHPC, and the recycled UHPC cement concrete can be prepared by sequentially adding the raw materialsinto a stirrer according to the components and parts by weight of the concrete, stirring and curing. According to the preparation method, waste is changed into valuables, through the steps, the wasteultra-high performance concrete is processed into regenerated cement which can be reused, the use amount of ordinary Portland cement can be reduced, the environmental problem caused by the waste ultra-high performance concrete can be solved, and reasonable utilization of resources is achieved.
本发明公开了一种再生UHPC水泥混凝土及其制备方法，属于建筑材料领域。该混凝土的组分及重量份数包括：再生UHPC水泥100份，水35‑40份，细骨料180‑220份，粗骨料280‑350份，减水剂0.5‑0.8份。通过将废弃的UHPC破碎、筛分、研磨、化学激发搅拌合后制备出再生UHPC水泥混凝土，在按照混凝土的组分及重量份数按顺序投放原料至搅拌机中搅拌、养护后方可制备出再生UHPC水泥混凝土，本发明能够把废弃的超高性能混凝土变废为宝，通过上述的步骤把废弃的超高性能混凝土加工成可再次使用的再生水泥，能够减少普通硅酸盐水泥的使用量，还能解决因废弃的超高性能混凝土造成的环境问题，实现资源的合理利用。
