Rubber powder ultrahigh-ductility mortar for building 3D printing and preparation thereof
The invention relates to rubber powder ultrahigh-ductility mortar for building 3D printing and preparation thereof. The mortar material comprises the following raw material components in parts by weight: 400-800 parts of cement, 100-200 parts of silica fume, 400-800 parts of fly ash, 80-400 parts of sand, 20-120 parts of rubber powder, 1-4 parts of a water reducing agent, 300-390 parts of water and 10-20 parts of polyethylene fibers. Compared with the prior art, with the optimal design of the formula, the ultrahigh ductility and high energy consumption capacity of the 3D printing rubber powdermortar material are further improved, and thus rib-free building 3D printing is achieved.
本发明涉及一种用于建筑3D打印的橡胶粉超高延性砂浆及其制备，该砂浆材料包括以下重量份数的原料组分：水泥400～800份，硅灰100～200份，粉煤灰400～800份，砂80～400份，橡胶粉20～120份，减水剂1～4份，水300～390份，聚乙烯纤维10～20份。与现有技术相比，本发明通过配方的优化设计，进一步提升3D打印橡胶粉砂浆材料的超高延性和高耗能能力，从而实现无筋的建筑3D打印。
