Sulfate-corrosion-resistant high-strength concrete doped with carbon nanofibers and preparation method of sulfate-corrosion-resistant high-strength concrete
The invention relates to the technical field of concrete, and discloses sulfate-corrosion-resistant high-strength concrete doped with carbon nanofibers and a preparation method of the sulfate-corrosion-resistant high-strength concrete. The concrete comprises the following components in percentage by mass: 15-20% of Portland cement, 20-25% of fine aggregate, 15-20% of coarse aggregate, 5-10% of modified carbon nanofibers, 1-3% of a polycarboxylate superplasticizer and the balance of water. The preparation method comprises the following steps: adding the Portland cement, the fine aggregate and the coarse aggregate into a stirrer, uniformly stirring, adding the polycarboxylate superplasticizer and the water, uniformly stirring and mixing, finally adding the modified carbon nanofibers, and uniformly stirring and mixing, thereby obtaining the product. The modified carbon nanofibers are added into the concrete, so that the sulfate corrosion resistance of the concrete is improved, and the mechanical strength of the concrete is also improved.
本发明涉及混凝土技术领域，公开了一种掺杂碳纳米纤维的抗硫酸盐侵蚀的高强度混凝土及其制备方法。包括按质量百分比计的下述组分：硅酸盐水泥15‑20%、细集料20‑25%，粗集料15‑20%，改性碳纳米纤维5‑10%，聚羧酸减水剂1‑3%，余量为水；先将硅酸盐水泥、细集料和粗集料加入搅拌机中搅拌均匀，然后加入聚羧酸减水剂和水，搅拌混合均匀，最后加入改性碳纳米纤维，搅拌混合均匀，即得。本发明通过在混凝土添加经过改性的碳纳米纤维，不仅提高混凝土的抗硫酸盐侵蚀性能，还提高混凝土的力学强度。
