Permeable concrete and preparation process thereof
The invention relates to the technical field of concrete, and particularly discloses a permeable concrete and a preparation process thereof. The permeable concrete comprises the following components in parts by weight: 800-1000 parts of coarse aggregate; 75-100 parts of water; 300-400 parts of Portland cement; 20-30 parts of a hydrophobic agent; 4-6 parts of a water reducing agent; 4-6 parts of anair entraining agent; and 5-8 parts of a buffer agent. The preparation process of the permeable concrete comprises the following steps: step 1, mixing and stirring the coarse aggregate and the Portland cement in proportion, then adding water and the water reducing agent in proportion, and stirring; step 2, adding the air entraining agent, the hydrophobic agent, the buffer agent and a self-repairing material into the mixture obtained in the step 1 in proportion, stirring, and controlling the stirring speed to be 100 r/min, so as to obtain a premix; and step 3, stirring the premix obtained in the step 2, controlling the stirring speed to be 100 r/min, paving the premix on a construction surface, and carrying out maintenance, compaction and molding to obtain the permeable concrete. The permeable concrete provided by the invention has the advantage of good frost resistance.
本申请涉及混凝土的技术领域，具体公开了一种透水混凝土及其制备工艺。透水混凝土包含以下重量份数的组分：粗骨料800‑1000份；水75‑100份；硅酸盐水泥300‑400份；疏水剂20‑30份；减水剂4‑6份；引气剂4‑6份；缓冲剂5‑8份。透水混凝土的制备工艺包括如下步骤：步骤1：按比例将粗骨料和硅酸盐水泥混合并搅拌，然后按比例加入水和减水剂并进行搅拌；步骤2：按比例向步骤1得到的混合物中加入引气剂、疏水剂、缓冲剂和自修复材料并搅拌，控制搅拌速度为100r/min，进而得到预混物；步骤3：搅拌步骤2得到的预混物，控制搅拌速度为100r/min，将预混物摊铺到施工面上，经养护密实成型后得到透水混凝土。本申请中的透水混凝土具有抗冻性能好的优点。
