Quick-setting and quick-hardening white UHPC and preparation method thereof
The invention provides quick-setting and quick-hardening white UHPC and a preparation method thereof. The white UHPC is prepared from white Portland cement (white cement), high belite sulphoaluminate cement, silica fume, quartz sand, quartz powder, aluminum sulfate, a water reducing agent, a defoaming agent and a retarder. The white UHPC disclosed by the invention is prepared by taking white cement as a main material, doping high belite sulphoaluminate cement and white silica fume to optimize a cementing material and adjusting proper mixing amounts of quartz aggregate and additives. The white UHPC disclosed by the invention not only has the characteristics of high strength and good durability, but also has the characteristics of small shrinkage, high forming speed and the like, and can meet the requirements of modern high-strength decorative concrete.
本发明提供了一种快凝快硬白色UHPC及制备方法，该白色UHPC由白色硅酸盐水泥(白水泥)、高贝利特硫铝酸盐水泥、硅灰、石英砂、石英粉、硫酸铝、减水剂、消泡剂以及缓凝剂组成。本发明的白色UHPC以白水泥为主，掺入高贝利特硫铝酸盐水泥与白硅灰来优化胶凝材料，通过调整合适的石英骨料及外加剂掺量制备而成。本发明的白色UHPC不仅具有强度高、耐久性好的特点，还具有收缩小、成型快等特点，能够满足现代高强度装饰性混凝土的需要。
