Concrete damage repair cement-based material for prefabricated part and application thereof
The invention relates to a concrete damage repair cement-based material for a prefabricated part and application thereof. The concrete damage repair cement-based material comprises the following components by weight: 100 to 150 g of water, 150 to 250 g of ordinary Portland cement, 200 to 400 g of high-belite sulphoaluminate cement, 50 to 100 g of a mineral admixture, 3 to 5 g of carbon fibers, 10to 30 g of an early strength agent, 20 to 60 g of an anti-sagging component, 2 to 5 g of a water reducer, 10 to 20 g of gypsum powder, 3 to 5 g ofmulti-walled hydroxylated carbon nanotubes, 20 to 40 gof anexpansion component, 2 to 6 g of Nano-SiO2 and 500 to 700 g offine aggregate. Compared with the prior art, the cement-based high-bonding-strength material disclosed by the invention has the advantages of short setting time, high strength development speed, high bonding strength with new and old concrete, good stability and no cracking, gives consideration to social benefits, and has a very good popularization value.
本发明涉及一种预制构件用混凝土损伤修复水泥基材料及其应用，按照成分重量有以下组成部分，水100～150g，普通硅酸盐水泥150～250g，高贝利特硫铝酸盐水泥200～400g，矿物掺合料50～100g，碳纤维3～5g，早强剂10～30g，抗流挂组分20～60g，减水剂2～5g，石膏粉10～20g，多壁羟基化碳纳米管3～5g，膨胀组分20～40g，Nano‑SiO22～6g，细骨料500～700g。与现有技术相比，本发明的水泥基高粘结强度材料具有凝结时间短，强度发展快，与新旧混凝土粘接强度高，稳定性好无开裂的优点，兼顾社会效益，具有很好的推广价值。
