Pervious concrete and preparation method thereof
The invention relates to the technical field of concrete, and provides pervious concrete and a preparation method thereof. The pervious concrete comprises 500 to 600 parts of coarse aggregate, 20 to 40 parts of fine aggregate, 20 to 30 parts of fly ash, 150 to 200 parts of a cementing material, 10 to 20 parts of a reinforcing agent, 10 to 20 parts of a water reducing agent, 140 to 175 parts of water and 220 to 300 parts of modified activated carbon powder slurry. The pervious concrete provided by the invention has good water permeability, and can effectively prevent water from accumulating on the road surface when being used for paving the road; and meanwhile, the pervious concrete also has good compressive strength and breaking strength, and is suitable for paving pavements with high-strength performance requirements.
本发明涉及混凝土技术领域，提供了一种透水混凝土及其制备方法。所述透水混凝土包括500‑600份的粗骨料、20‑40份的细骨料、20‑30份的粉煤灰、150‑200份的胶结材料、10‑20份的增强剂、10‑20份的减水剂、140‑175份的水和220‑300份的改性活性炭粉浆料。本发明提供的透水混凝土具有良好的透水性，用于铺设道路可有效防止路面积水；同时还具备较好的抗压强度和抗折强度，适合用于铺设高强度性能要求的路面。
