Super anti-permeability comb tooth polar expansion joint concrete with high stability
The invention relates to the technical field of concrete, in particular to high-stability super anti-permeability comb tooth polar expansion joint concrete which is mainly prepared from the following raw materials in parts by weight: 420-480 parts of Portland cement, 650-720 parts of lightweight aggregate, 1100-1200 parts of coarse aggregate, 180-200 parts of water, 100-130 parts of composite fiber, 90-100 parts of fine powder, 3-6 parts of calcium formate and 70-100 parts of admixture. The admixture can introduce a large number of tiny closed bubbles during concrete mixing, reduce the surface tension of a concrete mixture, change the workability of the concrete mixture and improve the strength of the concrete, due to blocking of the bubbles, the evaporation route of free water in the concrete becomes zigzag, tiny and dispersed, water seepage channels of the concrete are reduced, and the water seepage rate of the concrete is increased. According to the present invention, the composite fiber is added, such that the impermeability of the concrete is improved, the net-shaped structure of the composite fiber can be damaged during stirring to form the single fiber, the single fiber is mixed, the anti-leakage performance of the concrete is improved, the fine powder is added, the void ratio can be reduced, the concrete structure is compact, and the impermeability is improved.
本发明涉及混凝土技术领域，特别涉及一种稳定性强的超抗渗梳齿极伸缩缝混凝土,主要由如下重量份数的原料制成：硅酸盐水泥420‑480份、轻骨料650‑720份、粗骨料1100‑1200份、水180‑200份、复合纤维100‑130份、细粉料90‑100份、甲酸钙3‑6份、外加剂70‑100份；外加剂可以在混凝土搅拌时引入大量微小封闭的气泡，降低混凝土拌合物的表面张力，改变混凝土拌合物的和易性，提高混凝土的强度，由于气泡的阻隔，混凝土中自由水的蒸发路线变的曲折、细小、分散，减少了混凝土的渗水通道，从而提高了混凝土的抗渗性能，复合纤维的网状结构会在搅拌中得到破坏，形成单纤维，这些单纤维错综交杂，提高了混凝土的防渗漏性，加入细粉料，可降低空隙率，进而使混凝土的结构致密，提高抗渗性。
