Fair-faced concrete and preparation method thereof
The invention discloses fair-faced concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 30-40 parts of cement, 15-25 parts of volcanicash, 3-6 parts of nano hybrid hyperbranched polymer HB-SiO2, 75-85 parts of silica sand, 85-95 parts of coarse aggregate, 3-5 parts of basalt fibers, 1-3 parts of graphene oxide fibers, 7.5-8.5 partsof a composite additive, 15-20 parts of water, 1-3 parts of a carboxyl metal organic framework, 1-3 parts of zirconium citrate and 2-5 parts of zinc oxide nanofibers. The invention also provides a preparation method of the fair-faced concrete. The fair-faced concrete provided by the invention is better in comprehensive performance, higher in compressive strength and flowability, lower in bleedingrate, better in durability, environmental protection property and decorative effect, very good in appearance, smooth in surface and less in pores.
本发明公开了一种清水混凝土，其特征在于，包括按重量份计的如下组分制成：水泥30‑40份、火山灰15‑25份、纳米杂化超支化聚合物HB‑SiO2 3‑6份、硅砂75‑85份、粗骨料85‑95份、玄武岩纤维3‑5份、氧化石墨烯纤维1‑3份、复合外加剂7.5‑8.5份、水15‑20份、带羧基金属有机框架1‑3份、柠檬酸锆1‑3份、氧化锌纳米纤维2‑5份。本发明还提供了一种所述清水混凝土的制备方法。本发明提供的清水混凝土综合性能更佳，抗压强度和流动性更高，泌水率更低，耐久性、环保性和装饰效果更好，具有很好的外观，表面光滑、气孔较少。
