Carbon fiber reinforced ultra-high performance concrete and preparation method thereof
The invention relates to carbon fiber reinforced ultra-high performance concrete, which is prepared from the following components in parts by weight: 535-700 parts of a cementing material, 0-420 parts of aggregate, 70-150 parts of water, 7-35 parts of a water reducing agent and 1-10 parts of carbon fibers. The carbon fibers are a material with good chemical stability, and when corrosive ions such as Cl <-> and SO4 < 2-> invade into an interface between the carbon fibers and a hydration product, as the C element on the surface of the carbon fiber is very stable and does not chemically react with the Cl <-> and the SO4 < 2->, a carbon fiber-matrix interface structure on the surface of the carbon fiber reinforced ultra-high performance concrete is not easily damaged by corrosive ions in seawater and sea sand, and the carbon fiber reinforced ultra-high performance concrete has relatively high corrosion resistance. Carbon fibers and marine resources are jointly applied to the ultra-high performance concrete, the technical approach is novel, the marine resources can be effectively utilized and applied to marine buildings such as port buildings and island buildings, and remarkable social and economic benefits are achieved.
本发明涉及一种碳纤维增强的超高性能混凝土，以重量份计，包括以下组分，胶凝材料535～700份、骨料0～420份、水70～150份、减水剂7～35份和碳纤维1～10份。碳纤维本身是一种化学稳定性良好的材料，当Cl‑、SO42‑等侵蚀性离子侵入到碳纤维与水化产物的界面时，由于碳纤维表面C元素十分稳定，不与Cl‑、SO42‑发生化学反应，所以碳纤维增强的超高性能混凝土表面的碳纤维‑基体界面结构不容易受海水海砂中侵蚀性离子破坏，具有较强的耐蚀性。将碳纤维与海洋资源共同运用在超高性能混凝土之中，技术途径新颖，可以有效将海洋资源利用起来，并将其应用在港口建筑、岛屿建筑等海洋建筑，具有显著的社会和经济效益。
