High-weather-resistance basalt fiber concrete and preparation method thereof
The invention discloses high-weather-resistance basalt fiber concrete and a preparation method thereof, and belongs to the technical field of concretes.Silane coupling agent modified basalt fibers are added in the preparation process of the concrete, nano-flower-shaped microcracks appear on the surfaces of the modified basalt fibers, the specific surface area is increased, stress concentration is prevented, and the weather resistance of the concrete is improved; the interface bonding strength is effectively improved, a water reducing agent does not need to be added, the weather resistance of the concrete is improved, and the curing time can be shortened from conventional 3-5 d to 24-48 h.
本发明公开了一种高耐候性玄武岩纤维混凝土及其制备方法，属于混凝土技术领域，本发明在混凝土的制备过程中加入硅烷偶联剂改性的玄武岩纤维，改性玄武岩纤维表面现纳米花状的微裂纹，增大了比表面积，防止应力集中，有效增加界面粘结强度，无需加入减水剂，提高混凝土的耐候性，还可以缩短养护时间，由常规的3‑5d缩短至24‑48h。
