UHPC and preparation method thereof
The invention discloses UHPC (Ultra High Performance Concrete) and a preparation method thereof. The UHPC is prepared from the following raw materials in percentage by mass: 70 to 91 percent of premix, 3.5 to 8.8 percent of steel fiber, 0.2 to 1.1 percent of additive and 4.6 to 9.5 percent of water. The invention further discloses a preparation method. Through the UHPC preparation method, the stability of a UHPC mixture and the uniformity of steel fibers are ensured, and the defect that the working state is poor due to the fact that effective and uniform stirring cannot be achieved is overcome. The problem that the UHPC mixture easily shrinks excessively is solved by determining the mixing ratio, the wet joint size requirement is met, all links including raw materials, the production technology and construction process quality control are strictly controlled, the mechanical property, the working performance and the engineering quality are guaranteed, and good economic benefits are achieved. The used raw materials are easy to obtain, the production and construction process is convenient and fast, and common workers can carry out construction operation through simple training; the method is simple and easy to implement, and is suitable for pouring wet joints under various project environment conditions.
本发明公开了一种UHPC及其制备方法，包括以下质量百分数的原料：预混料70％～91％，钢纤维3.5％～8.8％，外加剂0.2％～1.1％，水4.6％～9.5％。还包括其制备方法。通过UHPC制备方法保证了UHPC拌合料的稳定性及钢纤维的均匀性，克服了无法有效搅拌均匀导致工作状态差的缺陷。通过配合比的确定解决了UHPC混凝土拌合物易出现的收缩过大等问题，保证了湿接缝尺寸要求，并从原材料、生产工艺、施工过程质量控制各个环节严格把关，保证了力学性能、工作性能、工程质量，具有良好的经济效益。所使用的原料易得，生产及施工工艺便捷，普通工人经过简单的培训即可进行施工操作；方法简单易行，适用于各种项目环境情况下湿接缝的浇筑。
