Impact-resistant basalt fiber reinforced concrete and preparation method thereof
The invention relates to impact-resistant basalt fiber reinforced concrete and a preparation method thereof. The impact-resistant basalt fiber reinforced concrete comprises the following components inparts by weight: 400-800 parts of cement, 80-170 parts of a mineral admixture; 500-1200 parts of fine aggregate; 90-1800 parts of coarse aggregate; 2-4 parts of basalt fiber; and 200-400 parts of water. According to the impact-resistant basalt fiber reinforced concrete, the basalt fiber has excellent impact resistance, and the impact failure load is higher than that of common concrete. The relative dynamic elastic modulus and the mass loss rate are obviously controlled under the condition of multiple freezing and thawing, the anti-freezing performance is outstanding, and the concrete has important significance in the fields of port deep wharfs, cross-sea bridges and the like.
本发明是关于一种抗冲击玄武岩纤维增强混凝土及其制备方法，所述抗冲击玄武岩纤维增强混凝土包含以下重量份的各组分：水泥400‑800份；矿物掺合料80‑170份；细骨料500‑1200份；粗骨料900‑1800份；玄武岩纤维2‑4份；水200‑400份。本发明所述的抗冲击玄武岩纤维增强混凝土，其玄武岩纤维具有优异的抗冲击性能，冲击破坏荷载比普通混凝有较高提升。在多次冻融条件下，相对动弹模量和质量损失率都得到显著控制，抗冻性能突出，用之于港口深码头，跨海大桥等领域有着重要的意义。
