Ultrahigh-ductility interface treatment mortar adaptive to fabricated steel structure and preparation method of ultrahigh-ductility interface treatment mortar
The invention provides ultrahigh-ductility interface treatment mortar adaptive to an assembled steel structure and a preparation method of the ultrahigh-ductility interface treatment mortar, and the mortar is prepared from the following components in parts by weight: 530-770 parts of a composite cementing material, 450-550 parts of graded sand, 0.4-0.6 part of a water reducing agent, 1-2.5 parts of a defoaming agent, 2-4 parts of cellulose ether, 2.5-5 parts of a composite volume stabilizer and 1-3.5 parts of nano-whisker modified PVA (Polyvinyl Alcohol) fibers, the composite cementing material comprises VAE (Vinyl Acetate Ethylene) redispersible latex powder and ordinary Portland cement; the composite volume stabilizer comprises a micro-expanding agent, a shrinkage reducing agent and nano SiO2. The mortar has excellent bonding performance and ductility performance, can effectively resist deformation and firmly bond the surface of a steel structure, and also reduces the generation of cracks and the risk of cracking. The preparation method of the mortar is simple, mechanical production is easy to realize, the construction process is diversified, and mechanical spraying can also be realized in a mode of combining roll coating, brush coating and blade coating.
本发明提供了一种适配于装配式钢结构的超高延性界面处理砂浆及其制备方法，该砂浆以重量份计，包括以下组分：复合胶凝材料530‑770份，级配砂450‑550份，减水剂0.4‑0.6份、消泡剂1‑2.5份，纤维素醚2‑4份，复合体积稳定剂2.5‑5份，纳米晶须改性PVA纤维1‑3.5份；所述复合胶凝材料包括VAE可再分散乳胶粉和普通硅酸盐水泥；所述复合体积稳定剂包括微膨胀剂、减缩剂、纳米SiO2。本砂浆具有优异的粘结性能和延性性能，能有效抵抗变形和牢固粘结钢结构表面，还减少裂纹产生和开裂的风险。本砂浆制备方法简单，容易实现机械化生产，施工工艺多样性，滚涂、刷涂、刮涂并举的方式，还可实现机械喷涂。
