Corrosion-resistant abrasion-resistant agent for concrete as well as preparation and application of corrosion-resistant abrasion-resistant agent
The invention discloses a corrosion-resistant abrasion-resistant agent for concrete as well as preparation and application of the corrosion-resistant abrasion-resistant agent, and relates to the technical field of concrete materials. The corrosion-resistant and abrasion-resistant agent for the concrete is prepared from the following raw materials in parts by weight: 60 to 70 parts of fly ash, 10 to 15 parts of slag powder, 8 to 10 parts of polyoxyethylene shrinkage reducing agent, 5 to 6 parts of expanding agent, 0.3 to 0.5 part of water reducing agent and 2 to 4 parts of nano silicon dioxide. The compressive strength, the splitting tensile strength, the ultimate tensile value, the anti-abrasion strength, the impact toughness ratio and the crack resistance of concrete prepared from the anti-corrosion anti-abrasion agent are improved, the self-generated volume deformation of the concrete can reach-72 * 10 <-6 > when the concrete is at the age of 180 days, the dry shrinkage rate of the concrete is remarkably reduced, and the service life of the concrete is prolonged. The performance of the concrete in all aspects is enhanced, and the possibility of erosion damage of the concrete is reduced, so that the service life of the hydraulic concrete is prolonged.
本发明公开了一种混凝土用耐蚀抗冲磨剂及其制备和应用，涉及混凝土材料技术领域。本发明的混凝土用耐蚀抗冲磨剂，包括以下重量份配比的原料：60‑70份粉煤灰，10‑15份矿渣粉，8‑10份聚氧乙烯类减缩剂，5‑6份膨胀剂，0.3‑0.5份减水剂和2‑4份纳米二氧化硅。应用本发明的耐蚀抗冲磨剂制备得到的混凝土的抗压强度、劈拉强度、极限拉伸值、抗冲磨强度、抗冲击韧性比、抗裂性能都得到的提高，混凝土自生体积变形至180d龄期时，可达‑72×10‑6，混凝土的干缩率显著降低，即混凝土的各方面性能均得到了增强，降低了混凝土产生侵蚀破坏的可能性，从而延长水工混凝土的使用寿命。
