Ultra-high performance lightweight concrete taking pottery sand as lightweight aggregate and preparation method thereof
The invention relates to ultra-high performance lightweight concrete taking pottery sand as a lightweight aggregate. The concrete comprises the following components in parts by weight: 524-749 parts of cement, 140-246 parts of ultrafine fly ash, 123-176 parts of micro silicon, 190-200 parts of shale pottery sand with the particle size of 0.60-1.18 mm, 190-200 parts of shale pottery sand with the particle size of 1.18-2.36 mm, 15-21 parts of a superplasticizer, and 104-173 parts of steel fiber. According to the ultra-high-performance lightweight concrete taking the pottery sand as the lightweight aggregate and the preparation method of the ultra-high-performance lightweight concrete, the problems that concrete is large in dead weight, large in shrinkage deformation, high in production cost,complex in production process and the like can be solved. The working performance of the concrete is improved while the ultrahigh strength is realized, and the construction requirement of self-leveling is met.
一种以陶砂为轻质骨料的超高性能轻质混凝土，所述混凝土包括以下重量份配比的组分：水泥524‑749份；超细粉煤灰140‑246份；微硅123‑176份；粒径0.60‑1.18mm页岩陶砂190‑200份；粒径1.18‑2.36mm页岩陶砂190‑200份；高效减水剂15‑21份；钢纤维104‑173份。本发明提供的一种以陶砂为轻质骨料的超高性能轻质混凝土及其制备方法，可以解决混凝土自重大，收缩变形较大，生产成本高，生产工艺复杂等问题。在实现超高强度的同时，改善混凝土的工作性能，满足自流平的施工要求。
