Anti-crack mortar and preparation method thereof
The invention discloses anti-crack mortar and a preparation method thereof. The anti-crack mortar provided by the invention comprises the following components in parts by mass: 100 parts of a cementing material; 0.4 to 20 parts of basalt-polyvinyl alcohol hydrogel core-shell type composite particles; 80 to 370 parts of sand; and 25 to 60 parts of water. The preparation method of the anti-crack mortar comprises the following step: uniformly mixing the cementing material, the basalt-polyvinyl alcohol hydrogel core-shell composite particles, the sand and the water to obtain the anti-crack mortar. The basalt-polyvinyl alcohol hydrogel composite particles are added into the anti-crack mortar, so that the anti-crack mortar has high compressive property and high anti-crack property, is good in durability and small in environmental load in the whole life cycle, and is simple in preparation process, low in cost and suitable for large-scale popularization and application.
本发明公开了一种抗裂砂浆及其制备方法。本发明的抗裂砂浆包括以下质量份的组分：胶凝材料：100份；玄武岩‑聚乙烯醇水凝胶核壳型复合颗粒：0.4份～20份；砂：80份～370份；水：25份～60份。本发明的抗裂砂浆的制备方法包括以下步骤：将胶凝材料、玄武岩‑聚乙烯醇水凝胶核壳型复合颗粒、砂和水混合均匀，即得抗裂砂浆。本发明的抗裂砂浆中添加有玄武岩‑聚乙烯醇水凝胶复合颗粒，兼具高抗压性能和高抗裂性能，耐久性好，全寿命周期的环境负荷小，且其制备工艺简单、成本低廉，适合进行大规模推广应用。
