High-molecular dense anti-cracking composite material and preparation method thereof
The invention relates to the technical field of concrete admixtures, and discloses a high-molecular dense anti-cracking composite material. Comprising the following raw materials in parts by weight: 6-8 parts of a silane coupling agent, 10-20 parts of polyester fibers, 6-8 parts of an expanding agent, 15-25 parts of polypropylene fibers, 20-30 parts of zeolite, 5-7 parts of silver powder, 4-6 parts of activated carbon, 2-4 parts of nano silicon dioxide, 20-30 parts of steel slag, 5-7 parts of an internal curing agent, 15-25 parts of montmorillonite, 7-9 parts of a permeable waterproof agent, 50-60 parts of fly ash and 6-8 parts of an airtight preservative. According to the high-molecular dense anti-cracking composite material and the preparation method thereof, the high-molecular dense anti-cracking composite material is divided into the anti-cracking fibers and the composite powder, the strength of formed concrete can be effectively improved after the anti-cracking fibers are added, the concrete is not prone to cracking, through cooperation of the composite powder and the additive, the overall performance of the concrete is improved, and cracking and leakage of the concrete are reduced; by adding the silane coupling agent, bridging between concrete aggregate and cement paste can be achieved in the concrete setting process.
本发明涉及混凝土外加剂技术领域，且公开了一种高分子密实抗裂合材，其特征在于，包括以下重量份数配比的原料：硅烷偶联剂6‑8份、聚酯纤维10‑20份、膨胀剂6‑8份、聚丙烯纤维15‑25份、沸石20‑30份、银粉5‑7份、活性炭4‑6份、纳米二氧化硅2‑4份、钢渣20‑30份、内养护剂5‑7份、蒙脱石15‑25份、渗透防水剂7‑9份、粉煤灰50‑60份和气密防腐剂6‑8份。该高分子密实抗裂合材及其制备方法，分成抗裂纤维和复合粉体两部分，抗裂纤维的加入后能够有效的提升形成混凝土的强度，使混凝土不易龟裂，通过复合粉体与添加剂的配合，提升了混凝土的整体性能，减少了混凝土的龟裂和渗漏性，经过硅烷偶联剂的添加，能够在混凝土凝结的过程中，起到混凝土骨料与水泥浆体之间的桥联。
