Concrete repair material, concrete repair coating and preparation method thereof
The invention relates to the technical field of concrete, in particular to a concrete repair material, a concrete repair coating and a preparation method thereof. The concrete repairing material comprises the following raw materials in parts by weight: 80-120 parts of cement, 10-30 parts of fine sand, 40-60 parts of limestone, 10-30 parts of a hydrophobic material, 30-50 parts of dispersed latex powder, 20-40 parts of an expanding agent, 10-20 parts of a defoaming agent and 6-9 parts of an early strength agent. The concrete repairing material disclosed by the invention has the advantages of short setting time, high early strength, water resistance, aging resistance and relatively long service lifetime.
本发明混凝土技术领域，具体涉及一种混凝土修复材料、混凝土修复涂层及其制备方法。按重量份计，所述混凝土修复材料的原料包括：水泥80‑120份、细砂10‑30份、石灰石40‑60份、疏水材料10‑30份、分散乳胶粉30‑50份、膨胀剂20‑40份、消泡剂10‑20份和早强剂6‑9份。本发明的混凝土修复材料具有凝结时间短、早期强度高、防水、耐老化和使用寿命较长的优点。
