High-strength quick-setting polymer mortar and preparation method thereof
The invention discloses a high-strength quick-setting polymer mortar. The polymer mortar comprises, by weight, 8-15 parts of aggregate, a composite excitation component and a gelling component, wherein the composite excitation component comprises, by weight, 2-4 parts of a sodium silicate dilute solution and 0.5-1 part of an alkaline solution; and the gelling component comprises, by weight, 1-2 parts of fly ash and 4-8 parts of mineral powder. The composite excitation component excites the gelling component to generate weight reduction reaction, so that excellent early strength is realized; and a C-A-S-H gel microstructure generated through a reaction can be tightly bonded to the surfaces of composite materials such as grids, rib materials and plates, so the bonding performance of the composite materials and a reinforced structure is guaranteed.
本发明公开一种高强速凝型的聚物砂浆，包括骨料、复合激发组分和胶凝组分，其中，所述骨料为8份～15份；所述复合激发组分包括：硅酸钠稀释溶液2份～4份，碱溶液0.5份～1份；所述胶凝组分包括：粉煤灰1份～2份，矿粉4份～8份，以上各组分以重量份计。本发明中的复合激发组分激发胶凝组分发生缩重反应，从而实现优异的早期强度；该反应生成的C‑A‑S‑H凝胶微结构可以紧密粘结在网格、筋材、板材等复合材料表面，从而保证复合材料与加固结构的粘结性能。
