Rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete and preparation method thereof
The invention relates to the technical field of building materials, and discloses rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete which is characterized in that the rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete comprises the following components: 400 to 500 parts of cement, 100 to 180 parts of water, 1200 to 1300 parts of stone, 500 to 600 parts of sand, 10 to 30 parts of an expanding agent, 0.5 to 2.5 parts of a water reducing agent, and 10 to 30 parts of waterproof nano powder, and the waterproof nano powder comprises the following components: mica powder, hydrophobic perlite powder, dimethyl silicone oil, a silane coupling agent and a surfactant. According to the rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete and the preparation method thereof, the waterproof nano powder is added, and the waterproof nano powder has a strong hydrophobic effect and a unique non-metal sheet structure, so that occlusion and connection among coarse and fine aggregates of the high-performance concrete can be effectively promoted, the contact area of a microstructure is enlarged, the porosity is reduced, and the compactness is improved.
本发明涉及建筑用料技术领域，且公开了一种刚性防水、抗冻融、防腐、自密实高性能混凝土，其特征在于，所述刚性防水、抗冻融、防腐、自密实高性能混凝土的组分包括水泥400‑500份，水100‑180份，石子1200‑1300份，砂子500‑600份，膨胀剂10‑30份，减水剂0.5‑2.5份，防水纳米粉10‑30份，所述防水纳米粉的组分包括云母粉、憎水珍珠岩粉、二甲基硅油、硅烷偶联剂和表面活性剂。该刚性防水、抗冻融、防腐、自密实高性能混凝土及其制备方法，通过防水纳米粉的添加防水纳米粉具有强烈的憎水作用和独特的非金属片状结构，能有效促进高性能混凝土粗细骨料间的咬合、连接、扩大微观结构接触面积降低孔隙率提高密实性。
