Cement-based structure repairing mortar
The invention provides cement-based structure repairing mortar. The cement-based structure repairing mortar is prepared from the following raw materials in percentage by weight: 40-50% of a cement-based material, 20-30% of sand, 2-4% of quick lime, 1-2% of a shrinkage reducing agent, 8-12% of an expanding agent, 3-5% of a penetrating agent and 15-20% of water. The repairing mortar provided by the invention not only has good permeability and ensures that the cement mortar can fill all gaps in a cement-based structure, but also has good expansion performance and shrinkage performance, and ensures that secondary damage to the cement-based structure due to excessive expansion and shrinkage after the cement mortar is filled is avoided, the repairing quality of the cement mortar is improved.
本发明提供了一种水泥基结构修补砂浆，该修补砂浆由如百分比含量的原料制成：水泥基料40‑50％、砂料20‑30％，生石灰2‑4％、减缩剂1‑2％、膨胀剂8‑12％、渗透剂3‑5％、水15‑20％。本发明所述的修补砂浆不仅具有良好的渗透性能，确保水泥砂浆能够填补到水泥基结构中的所有空隙中，而且具有良好的膨胀性能以及缩减性能，确保在水泥砂浆填补后不会因膨胀以及收缩过度而对水泥基结构造成二次损坏，提高水泥砂浆的修补质量。
