The invention belongs to the technical field of concrete, and provides an environment-friendly colored pervious concrete preparation method, which comprises: 1, crushing waste concrete through a crushing device to remove impurities, and screening through a screening device to obtain a coarse aggregate and a fine aggregate; 2, in the process of mixing and stirring 1200-1500 parts of coarse aggregate, 80-100 parts of fine aggregate, 5-10 parts of anti-crack fibers and 2-5 parts of single-walled carbon nanotubes, a silane coupling agent solution is sprayed, and modified water-permeable aggregate is obtained; step 3, uniformly mixing the modified water-permeable aggregate, cement, water and a water reducing agent according to a ratio of (80-100): (15-20): (10-15): (0.5-1) at a rotating speed of 120-150r/min to obtain a concrete backing material; the anti-crack fiber improves the pressure resistance of the concrete and also can enhance the binding power of cement paste and aggregate, and the single-walled carbon nanotubes increase the water permeability and play a role in water permeability.
本发明属于混凝土技术领域，提供了一种环保型彩色透水混凝土制备方法，包括以下步骤：步骤一：将废弃混凝土通过粉碎设备粉碎除杂后，通过筛分设备筛分得到粗骨料和细骨料；步骤二：将粗骨料1200‑1500份、细骨料80‑100份、抗裂纤维5‑10份和单壁碳纳米管2‑5份混合搅拌的过程中，喷洒硅烷偶联剂溶液，得到改性透水性骨料；步骤三：以比例为80‑100：15‑20：10‑15：0.5‑1的改性透水性骨料、水泥、水和减水剂，通过120～150r/min的转速混合均匀，得到混凝土底料；抗裂纤维提高了混凝土的抗压性，还能增强水泥浆体与骨料的粘结力，单壁碳纳米管增加了透水率，起到透水的作用。
