Anti-crack concrete and preparation method thereof
The invention provides anti-crack concrete and a preparation method thereof, and belongs to the technical field of concrete. The concrete comprises the following components in parts by weight: 100-150 parts of water, 200-400 parts of cement, 30-50 parts of epoxy resin modified polypropylene fiber, 10-20 parts of reinforced fiber, 9-14 parts of a water reducing agent, 7-10 parts of an expanding agent, 30-70 parts of fly ash, 30-70 parts of coarse aggregate, 20-50 parts of fine aggregate and 0.1-0.3 part of sodium dioctyl sulfosuccinate. In the anti-crack concrete, the modified polypropylene fibers are uniformly distributed in a concrete matrix, and the hydration reaction speed is increased by forming a fiber net structure, so that the crack resistance and impermeability of the concrete are remarkably improved, and the strength of the concrete is improved.
本发明提出了一种抗裂混凝土及其制备方法，属于混凝土技术领域，包括以下重量份的组分：水100‑150份、水泥200‑400份、环氧树脂改性聚丙烯纤维30‑50份、增强纤维10‑20份、减水剂9‑14份、膨胀剂7‑10份、粉煤灰30‑70份、粗骨料30‑70份、细骨料20‑50份、二辛基琥珀酸磺酸钠0.1‑0.3份。本发明抗裂混凝土中，改性聚丙烯纤维均匀分布在混凝土基质中，通过形成纤维网结构，提高水化反应速度，从而显著提高了混凝土的抗裂性和抗渗性，增加了混凝土强度。
