3D printing rubber concrete and preparation method thereof
The invention provides 3D printing rubber concrete and a preparation method thereof. The 3D printing rubber concrete is prepared from the following raw materials in parts by weight: 763 to 954 parts of fine aggregate, 19 to 78 parts of rubber powder, 1 to 3 parts of a water reducing agent, 320 to 350 parts of water and 940 to 970 parts of cement, wherein the rubber powder is adopted to replace components with corresponding particle sizes in the fine aggregate. By optimizing the raw material composition, the rubber powder with different particle sizes and substitution rates is adopted to replace the components with corresponding particle sizes in the fine aggregate, so that the defects of the existing 3D printing rubber concrete in particle size and substitution rate selection are overcome, and the fluidity, constructability, extrudability and strength of the 3D printing rubber concrete are ensured.
本发明提供了一种3D打印的橡胶混凝土及其制备方法。本发明的3D打印的橡胶混凝土，包括如下重量份的原料：细骨料763‑954份，橡胶粉19‑78份，减水剂1‑3份、水320‑350份和水泥940‑970份；其中，采用橡胶粉替换细骨料中对应粒径的组分。本发明通过优化原料组成，采用不同粒径和取代率的橡胶粉替换细骨料中对应粒径的组分，解决了现有3D打印的橡胶混凝土在粒径和取代率选择上的不足，保证了3D打印的橡胶混凝土的流动性、可建造性、可挤出性和强度。
