Freeze-thaw-resistant high-content bunchy basalt fiber reinforced concrete
The invention discloses freeze-thaw-resistant high-content bunchy basalt fiber reinforced concrete, and belongs to the technical field of concrete processing. The freeze-thaw-resistant high-content bundle-shaped basalt fiber reinforced concrete is used for solving the technical problems that in the prior art, the frost resistance of concrete is poor, and the mixing amount of basalt fibers in the concrete needs to be further increased. Comprising the following components in parts by weight: 70-78 parts of coarse aggregate, 30-35 parts of fine aggregate, 25-30 parts of composite cement, 0.2-0.3 part of an additive, 0.8-1.2 parts of bunchy reinforced fibers and 15-20 parts of water. The basalt fibers are reinforced and modified, the mixing amount of the basalt fibers in the concrete is greatly increased, and the mechanical property and freeze-thaw resistance of a concrete test piece are effectively enhanced by optimizing the particle size ratio of the coarse aggregate and matching the coarse aggregate with the composite cement and the bundle-shaped reinforced fibers.
本发明公开了一种抗冻融高掺量束状玄武岩纤维增强混凝土，属于混凝土加工技术领域。本发明用于解决现有技术混凝土的抗冻性能差和玄武岩纤维在混凝土中掺量有待进一步提高的技术问题，一种抗冻融高掺量束状玄武岩纤维增强混凝土，包括以下重量份成分：粗骨料70‑78份、细骨料30‑35份、复合水泥25‑30份、外加剂0.2‑0.3份、束状增强纤维0.8‑1.2份和水15‑20份。本发明通过对玄武岩纤维进行增强改性，较大幅度提高了玄武岩纤维在混凝土中的掺量，并通过优化粗骨料粒径配比与复合水泥、束状增强纤维相互配合，有效地增强了混凝土试件的力学性能与抗冻融性能。
