Low-shrinkage surface layer decoration white ultra-high performance concrete spraying material and preparation method thereof
The invention provides a low-shrinkage surface layer decoration white ultra-high performance concrete spraying material, which is prepared from the following ingredients in parts by weight: 700 to 800 parts of white cement, 130 to 160 parts of white silica fume, 120 to 150 parts of quartz powder, 15 to 25 parts of titanium dioxide, 650 to 750 parts of shrinkage reducing ingredients, 600 parts of white quartz sand, 1 to 1.5 parts of antifoaming agents, 8 to 12 parts of polycarboxylic acid water reducing agents and 200 to 220 parts of water. The shrinkage reducing component is obtained by ultrasonically mixing high-alumina bauxite aggregate and white sulphoaluminate cement according to a mass ratio of 1: (0.1-0.15) in a silane coupling agent and drying. The spraying material has the advantages of low shrinkage rate, 180 d drying shrinkage of less than-90 [mu] epsilon, excellent volume stability, effective prevention of cracks on the surface of the surface decoration white ultra-high performance concrete, and excellent durability and construction performance.
本发明提供了一种低收缩面层装饰白色超高性能混凝土喷涂材料，包括以下重量份的组分：白水泥700‑800份，白硅灰130‑160份，石英粉120‑150份，钛白粉15‑25份，降缩组分650‑750份，白色石英砂600份，消泡剂1‑1.5份，聚羧酸减水剂8‑12份，水200‑220份，所述降缩组分由高铝矾土骨料和白色硫铝酸盐水泥按照质量比1：(0.1‑0.15)于硅烷偶联剂中超声混合、烘干得到。该喷涂材料的收缩率较低，180d干燥收缩小于‑90με，体积稳定性能优异，能够有效避免面层装饰白色超高性能混凝土表面产生裂纹、耐久性能及施工性能优异。
