High-ductility fiber-reinforced recycled mortar for 3D printing of buildings and preparation method for high-ductility fiber-reinforced recycled mortar
The invention relates to the fields of 3D printing of buildings and resourceful utilization of wastes, specifically to high-ductility fiber-reinforced recycled mortar for 3D printing of the buildingsand a preparation method for the high-ductility fiber-reinforced recycled mortar. The high-ductility fiber-reinforced recycled mortar capable of being used for 3D printing of the buildings comprises the following components in parts by weight: 550 to 800 parts of cement, 200 to 450 parts of fly ash, 1000 parts of reclaimed sand, 10 to 16 parts of regenerated PET short fibers, 1.0 to 1.5 parts of adefoaming agent, 0.5 to 3.8 parts of a water reducing agent, 0.5 to 0.7 part of sodium gluconate, 4.0 to 7.0 parts of nanometer clay, 1.1 to 1.6 parts of cellulose and 300 to 600 parts of water. According to the invention, recycled PET short fibers are doped into recycled mortar for 3D printing of the buildings, and additives are added for adjustment, so the material meets the requirements of pumpability, extrudability and constructability of 3D printing ink of the buildings, and has the advantage of high ductility.
本发明涉及建筑3D打印及废弃物资源化领域，尤其涉及一种建筑3D打印用高延性纤维增强再生砂浆及其制备方法。可用于建筑3D打印的高延性纤维增强再生砂浆，以重量份计，包括以下组分：水泥：550‑800份；粉煤灰：200‑450份；再生砂：1000份；再生PET短纤维：10‑16份；消泡剂：1.0‑1.5份；减水剂：0.5‑3.8份；葡萄糖酸钠：0.5‑0.7份；纳米黏土：4.0‑7.0份；纤维素：1.1‑1.6份；水：300‑600份。通过将再生PET短纤维掺入到建筑3D打印再生砂浆中，并辅以添加剂进行调节，使得该种材料既满足了建筑3D打印油墨可泵送性、可挤出性和可建造性的要求，又具有高延性的优点。
