Basalt fiber concrete and preparation method thereof
The invention discloses basalt fiber concrete and a preparation method thereof, and relates to the technical field of concrete. The basalt fiber concrete is prepared from the following raw materials in parts by mass: 350 to 380 parts of cement, 650 to 800 parts of fine aggregate, 1000 to 1200 parts of coarse aggregate, 5 to 7 parts of water reducing agent and 2.5 to 3 parts of basalt fiber. The basalt fibers are added into the concrete, so that the effect of filling large gaps can be achieved, the effect of pore communication in the concrete is inhibited, and diffusion of chloride ions in the concrete is inhibited; the basalt fibers are mutually lapped in the concrete to form a network structure, so that the integrity of the concrete is improved, and the compressive strength of the concrete is further improved. By reasonably limiting the specific raw material composition, the strength of the concrete is improved while the chloride ion diffusion resistance of the concrete is improved, so that the concrete is suitable for being used in saline-alkali soil.
本发明公开了一种玄武岩纤维混凝土及其制备方法，涉及混凝土技术领域。按质量份数计，玄武岩纤维混凝土的原料包括：水泥350‑380份，细集料650‑800份，粗集料1000‑1200份，减水剂5‑7份，玄武岩纤维2.5‑3份。本发明通过向混凝土中添加玄武岩纤维，能够起到填充较大空隙的作用，抑制混凝土中孔隙的连通的作用，从而抑制氯离子在混凝土中的扩散；并且玄武岩纤维在混凝土中相互搭接，构筑成网络结构，提升混凝土的整体性，进而提升混凝土的抗压强度。本发明通过合理限定具体的原料组成，在提高混凝土耐氯离子扩散性能的同时还提高了混凝土的强度，使其适用于在盐碱地使用。
