The invention relates to the field of building materials, and particularly discloses sponge city pervious concrete and a construction process thereof. The sponge city pervious concrete comprises the following substances in parts by weight: 30-50 parts of aggregate, 20-30 parts of cement, 3-5 parts of a reinforcing agent, 1-2 parts of a water reducing agent, 2-3 parts of a foaming agent and 10-20 parts of water, wherein the reinforcing agent comprises fly ash and needle-like wollastonite; the construction process comprises the following steps: s1, pre-foaming; s2, preparing concrete; and s3, laying. The pervious concrete can be used in the fields of roads, bridges and the like, and has excellent water absorption and storage effects and good strength; in addition, according to the construction technology, through a pre-foaming mode, foam is more stable and uniform, and then the effect that the concrete absorbs water through pores is better.
本申请涉及建筑材料的领域，具体公开了一种海绵城市透水混凝土及其施工工艺。一种海绵城市透水混凝土包括以下重量份物质：30‑50份骨料、20‑30份水泥、3‑5份增强剂、1‑2份减水剂、2‑3份发泡剂和10‑20份水，所述增强剂包括粉煤灰和针状硅灰石；其施工工艺为：S1、预发泡；S2、混凝土配置；S3、铺设。本申请的透水混凝土可用于道路、桥梁等领域，其具有较为优异的吸水、蓄水效果以及较佳的强度；另外，本申请的施工工艺通过预发泡的方式，使得泡沫更加稳定且均匀，进而混凝土通过孔隙吸水的效果更佳。
