Composition for heavy-load terrace repairing mortar, heavy-load terrace repairing mortar as well as preparation method and application of heavy-load terrace repairing mortar
The invention relates to the field of terrace mortar materials, and discloses a composition for heavy-load terrace repairing mortar, the heavy-load terrace repairing mortar and a preparation method and application of the heavy-load terrace repairing mortar. The composition contains a composition A and a third volume deformation control aid, the composition A contains cement, an active admixture, sand, a toughening agent, a water reducing agent, a defoaming agent, a thickening agent, anti-crack fibers, a first volume deformation control aid and a second volume deformation control aid; wherein the first volume deformation control auxiliary agent is a three-expansion-source expanding agent, the second volume deformation control auxiliary agent contains 56-67 wt% of an internal curing agent and 33-44 wt% of a water evaporation inhibitor, and the third volume deformation control auxiliary agent contains 91-97 wt% of a shrinkage reducing agent and 3-9 wt% of a plastic expanding agent. The heavy-load terrace repairing mortar provided by the invention is low in shrinkage and stable in volume, and the cracking problem occurring in a heavy-load terrace repairing and renovating project is reduced.
本发明涉及地坪砂浆材料领域，公开了一种重载地坪修补砂浆用组合物、重载地坪修补砂浆及其制备方法和应用。该组合物中含有组合物A和第三体积形变控制助剂；所述组合物A中含有水泥、活性掺合料、砂、增韧剂、减水剂、消泡剂、增稠剂、抗裂纤维、第一体积形变控制助剂和第二体积形变控制助剂；其中，第一体积形变控制助剂为三膨胀源膨胀剂，第二体积形变控制助剂中含有56～67wt％的内养护剂和33～44wt％的水分蒸发抑制剂，第三体积形变控制助剂中含有91～97wt％的减缩剂和3～9wt％的塑性膨胀剂。本发明提供的重载地坪修补砂浆收缩低、体积稳定，减少重载地坪进行修补翻新工程中发生的开裂问题。
