Preparation method of high-strength corrosion-resistant concrete
The invention discloses a preparation method of high-strength corrosion-resistant concrete, which comprises the following steps: uniformly stirring and mixing 55-64 parts of aggregate, 18-22 parts of filler, 12-18 parts of cementing agent and 0.15-1 part of nano silicon dioxide modified nylon fiber, pouring, vibrating and molding, demolding, curing and the like to obtain the high-strength corrosion-resistant concrete. The poly (amide-imide) grafted silicon dioxide with excellent mechanical properties is added into the concrete, and the silicon dioxide nylon composite fiber forms a reinforced phase in the concrete, so that the effects of filling gaps of the concrete and supporting a framework are achieved, and the compressive strength of the concrete is remarkably improved. And after being soaked in sulfuric acid, the concrete still keeps very high compressive strength and strength retention rate.
本发明公开了一种高强度耐腐蚀混凝土的制备方法，包括55‑64份骨料、18‑22填料、12‑18份的胶结剂、0.15‑1份纳米二氧化硅改性尼龙纤维，经过搅拌混匀，浇筑，振捣成型，脱模、养护等工艺，得到高强度耐腐蚀混凝土；混凝土中加入了力学性能优异的聚(酰胺‑酰亚胺)接枝二氧化硅，二氧化硅尼龙复合纤维在混凝土中形成增强相，起到填充混凝土间隙，支撑骨架的作用，显著提高了混凝土的抗压强度。并且经过硫酸浸泡后，混凝土仍然保持很高的抗压强度和强度保持率。
