Normal-temperature curing C200-grade high-fluidity ultra-high-performance concrete and preparation method thereof
The invention discloses normal-temperature cured C200-grade high-fluidity ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete is mainly prepared from the following components in parts by weight: 800 to 1500 parts of powder material, 500 to 1500 parts of fine aggregate, 30 to 100 parts of additive, 112 to 240 parts of water and 234 to 468 parts of steel fiber. According to the invention, the dosage of each raw material is determined through a method for determining the mass ratio of different powder materials to different fine aggregates and a fiber compound doping principle of steel fibers. The invention also provides a preparation method of the ultra-high performance concrete. The ultrahigh-performance concrete can reach the C200 strength grade through normal-temperature curing, the slump expansion degree reaches 600-800 mm, much inconvenience in the steam curing process is avoided, and the ultrahigh-performance concrete is suitable for C200-grade ultrahigh-performance concrete construction engineering requiring cast-in-place and normal-temperature curing.
本发明公开了一种常温养护C200级高流动性超高性能混凝土及其制备方法。所述超高性能混凝土主要由800～1500重量份粉体材料、500～1500重量份细骨料、30～100重量份外加剂、112～240重量份水以及234～468重量份钢纤维组成。本发明通过不同粉体材料和不同细骨料质量比的确定方法以及钢纤维的纤维复掺原则，确定了各原料的用量。本发明还提供了超高性能混凝土的制备方法。本发明的超高性能混凝土通过常温养护即可达到C200强度等级，且坍落扩展度达600～800mm，免去蒸汽养护过程中的诸多不便，适用于要求现场浇筑且常温养护的C200级超高性能混凝土施工工程。
