Steel fiber and basalt fiber double-doped colored ultra-high performance concrete and preparation method thereof
The invention discloses steel fiber and basalt fiber double-doped colored ultra-high performance concrete, and the concrete is prepared from the following ingredients in parts by weight: 100 parts of cement, 5.84 to 35.3 parts of silica fume, 8.08 to 100 parts of mineral admixtures, 105.16 to 258.83 parts of fine aggregates, 1 to 3 parts of water reducing agents, 10 to 20 parts of pigments, 19.86 to 47.06 parts of water, 0.8 to 1.2 volume percent of steel fibers and 0.05 to 0.2 volume percent of basalt fibers. The preparation method comprises the following steps: (1) dry material mixing: weighing the cement, the silica fume, the mineral admixture, the fine aggregate, the solid water reducing agent and the pigment according to the weight ratio, mixing and uniformly stirring; (2) water adding and stirring: after the dry materials are uniformly mixed, adding water into the dry materials under a stirring condition, and uniformly stirring; (3) adding of the fibers: adding the steel fibers and the basalt fibers under a stirring condition, and uniformly stirring until the mixture is stable, thereby obtaining the composite material.
本发明公开了一种钢纤维和玄武岩纤维双掺彩色超高性能混凝土：包括如下重量份的组分：水泥100份、硅灰5.84～35.3份、矿物掺合料8.08～100份、细集料105.16～258.83份、减水剂1～3份、颜料10～20份、水19.86～47.06份，还包括体积掺量0.8％～1.2％的钢纤维和0.05％～0.2％的玄武岩纤维。还公开了其制备方法：(1)干料拌合：将水泥、硅灰、矿物掺合料、细集料、固体减水剂及颜料按重量比称取后混合并拌匀；(2)加水拌合：待干料混匀后，在搅拌条件下将水加入干料中，拌匀；(3)加入纤维：在搅拌条件下加入钢纤维和玄武岩纤维，搅拌均匀至混合物稳定，即得。
