Single-component high-strength impervious thin layer repair mortar as well as preparation method and application thereof
The invention belongs to the field of concrete repairing materials, and discloses single-component high-strength impervious thin-layer repairing mortar as well as a preparation method and application thereof. The repair mortar is prepared from 400 to 500 parts of special cement, 0 to 60 parts of heavy calcium carbonate, 400 to 500 parts of aggregate, 30 to 40 parts of redispersible rubber powder, 2 to 5 parts of fiber, 0.6 to 1.0 part of cellulose ether, 2.3 to 6.9 parts of other auxiliary agents and 160 to 180 parts of water, wherein the other auxiliary agents comprise 2 to 5 parts of a retarder and 0.3 to 0.8 part of an early strength coagulant, and optionally comprise 0.2 to 0.6 part of a water reducing agent and 0.2 to 0.5 part of a defoaming agent. The waterproof and anti-seepage agent has good compatibility with concrete and high bonding strength, the corrosion resistance and the waterproof and anti-seepage performance of a concrete structure are improved, meanwhile, the concrete repairing procedures are reduced, the construction period is shortened, the durability of the concrete structure is improved, and the service life of the concrete structure is prolonged.
本发明属于混凝土修补材料领域，公开了一种单组分高强抗渗薄层修补砂浆及制备方法和应用。该修补砂浆包括特种水泥400‑500份，重钙0‑60份，骨料400‑500份，可再分散胶粉30‑40份，纤维2‑5份，纤维素醚0.6‑1.0份，其他助剂2.3‑6.9份和水160‑180份；所述其他助剂包括缓凝剂2‑5份和早强促凝剂0.3‑0.8份，以及任选地包括减水剂0.2‑0.6份和消泡剂0.2‑0.5份。本发明与混凝土具有很好的相容性和高强的粘结强度，增加了混凝土结构的耐腐蚀性和防水抗渗性能，同时减少混凝土修补工序和工期，增加了混凝土结构的耐久性和使用寿命。
