High-ductility quick-setting quick-hardening concrete repairing material
The invention relates to the technical field of building materials, and discloses a high-ductility quick-setting quick-hardening concrete repairing material. The material is prepared from the following raw materials in parts by weight: 30 to 80 parts of fly ash, 90 to 140 parts of quartz sand and 70 to 120 parts of water. According to the high-ductility quick-setting quick-hardening concrete repairing material, by adding Portland cement, aluminate cement and dihydrate gypsum, a large amount of ettringite and hydrated calcium aluminate can be generated in the early melting stage of water, so high early strength can be obtained; the ettringite contains a large amount of crystal water and has certain expansion performance for a system, so good adhesion with foundation concrete can be formed, and the purpose of good adhesion is achieved; and by adding a certain amount of mineral powder, a pore structure can be refined, and the mineral powder can react with calcium hydroxide and other substances to generate hydrated calcium silicate gel (volcanic ash effect) so as to further improve the compactness and the ion erosion resistance of mortar, and the purpose of good compactness and ion erosion resistance of the mortar is achieved.
本发明涉及建筑材料技术领域，且公开了一种高延性快凝快硬混凝土修补材料，包括以下重量份数配比的原料：粉煤灰30‑80份、石英砂90‑140份、水70‑120份。该高延性快凝快硬混凝土修补材料，通过加入硅酸盐水泥、铝酸盐水泥和二水石膏，水的融化早期可以生成大量的钙矾石和水化铝酸钙，因此能够获得较高的早起强度，且钙矾石含有大量结晶水，对体系而言具有一定的膨胀性能，可以和基础混凝土形成很好的粘接，实现了粘接性较好的目的，通过加入一定量的矿粉，可以细化孔结构，且可以与氢氧化钙等物质发生反应，生成水化硅酸钙凝胶(火山灰效应)，进一步提高砂浆的密实度和抗离子侵蚀性能，实现了砂浆的密实度和抗离子侵蚀性能好的目的。
