3D printing desert sand ultra-high ductility concrete and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to 3D printing desert sand ultrahigh-ductility concrete and a preparation method thereof.According to the ultrahigh-ductility concrete, desert sand is used for completely replacing quartz sand, the sand-cement ratio can reach 0.9, the influence on the environment is reduced while the material cost is reduced, meanwhile, the tensile strain capacity of the concrete can reach 9%, and the concrete has the good ductility. The strain level of common steel bars is achieved, construction of a concrete structure without steel bars can be achieved, and the method is suitable for the field of 3D printing of concrete structures.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种3D打印沙漠砂超高延性混凝土及其制备方法，本发明超高延性混凝土使用沙漠砂完全替代石英砂，且砂胶比可达0.9，降低材料成本的同时减少对环境的影响，同时其拉伸应变能力可达9%，达到普通钢筋的应变水平，可以实现无钢筋的混凝土结构建造，适用于混凝土结构的3D打印领域。
