Environment-friendly pervious concrete and preparation method thereof
The invention discloses environment-friendly pervious concrete and a preparation method thereof. The pervious concrete comprises the following components in parts by mass: 1646 parts of aggregate; 1.670-2.143 parts of a water reducing agent; 334-545 parts of a cementing material; the target void ratio of the pervious concrete is 15%-25%, and the water cement ratio is 0.25-0.3. The pervious concrete disclosed by the invention has high bonding performance among aggregates, the compressive strength of the permeable concrete is obviously improved compared with that of traditional recycled aggregate permeable cement concrete, and the permeable concrete has better flexibility and good flexural tensile strength.
本发明公开了一种环境友好型透水混凝土及其制备方法，透水混凝土包括如下质量份数的组分：骨料1646份；减水剂1.670‑2.143份；胶凝材料334‑545份；所述透水混凝土的目标空隙率为15％‑25％，水灰比为0.25‑0.3。根据本发明的透水混凝土骨料间粘结性能高，比传统再生骨料透水水泥混凝土的抗压强度明显提升，具有较好柔韧性，弯拉强度好。
