The invention discloses an ultra-high performance concrete produced from construction waste micro powder. The ultra-high performance concrete is prepared from the following raw materials in percentageby mass: 25-40% of cement, 2-6% of silica fume, 2-6% of ultrafine red brick micro powder, 25-35% of regenerated fine sand and 25-35% of silica sand, wherein the water-binder ratio is 0.18-0.23. The formula is reasonable, the cement, the silica fume, the superfine red brick micro-powder, the recycled fine sand and the silica sand are ingeniously mixed, the superfine red brick micro-powder preparedfrom the waste red bricks is introduced, the specific surface area is large, the activity is high, the comprehensive performance of concrete is effectively improved, the problem of recycling of the waste red bricks is effectively solved, and the purposes of protecting the environment and recycling resources are achieved, so that the environment is protected, the cost is greatly reduced, the construction is easy, good economic benefits and social benefits are achieved, and wide application and popularization are facilitated.
本发明公开了一种利用建筑垃圾微粉生产超高性能混凝土，其包括以下质量百分比原料：水泥25～40％，微硅粉2～6％，超细红砖微粉2～6％，再生细砂25～35％，硅砂25～35％，水胶比为0.18～0.23。本发明的配方合理，巧妙将水泥、微硅粉、超细红砖微粉、再生细砂和硅砂相混合，引入废旧红砖制成的超细红砖微粉，比表面积大、活性高，有效提高混凝土综合性能，而且也有效解决废旧红砖再生利用的问题，达到了保护环境，资源再生利用的目的，不仅保护环境，还大大降低成本，易于施工，有良好的经济效益和社会效益，利于广泛推广应用。
