Preparation method of ultrahigh-toughness polymer mortar
The invention discloses a preparation method of ultrahigh-toughness polymer mortar, and relates to the technical field of repair mortar. The ultrahigh-toughness polymer mortar is prepared from the following components in parts by weight: 810-1050 parts of ordinary Portland cement, 130-270 parts of composite mineral admixture, 200-330 parts of water, 600-800 parts of quartz sand, 50-200 parts of composite additive and 13-45 parts of composite fiber, wherein the water-binder ratio is 0.31-0.44, and the binder-sand ratio is 0.7-0.9. The mortar prepared by the invention can effectively improve theinterface bonding force and anchoring force of repair mortar; meanwhile, early-stage and long-term shrinkage of the material is controlled, and cracking and disengaging are avoided.
本发明公开了一种超高韧性聚合物砂浆的制备方法，它涉及修补砂浆技术领域。包括以下重量配比的组分组成：普通硅酸盐水泥810‑1050份，复合矿物掺和料130‑270份，水200‑330份；石英砂600‑800份，复合外加剂50‑200份，复合纤维13‑45份，其中水胶比为0.31‑0.44，胶砂比为0.7‑0.9。本发明制备得的砂浆能够有效提升修补砂浆的界面粘结力和锚固力；同时控制材料早期与长期收缩，避免开裂与脱空。
