Anti-cracking and anti-blocking pervious concrete and preparation method thereof
The invention provides anti-cracking and anti-blocking pervious concrete and a preparation method thereof. The raw materials comprise cement, recycled aggregate, wood fibers, an anti-blocking agent and water, and the anti-blocking agent contains amorphous high-activity free silicon oxide and a material with high adsorption performance. The preparation method comprises the following steps: S1, drying and dehydrating garden waste to obtain a first product; S2, cutting the first product into blocks to obtain a second product; S3, mixing broken stones with the second product, adding a small amountof water, and carrying out stirring to obtain a third product; and S4, adding the cement, the anti-blocking agent and the water into the third product, and carrying out stirring to obtain the anti-cracking and anti-blocking pervious concrete; and S5, laying the anti-cracking anti-blocking pervious concrete on the ground. Technicians in the field aim to develop the anti-cracking and anti-blockingpervious concrete and the preparation method thereof in order to solve the problem of saltpetering of the pervious concrete and the problem on how to resist to formation of a biological membrane in the pervious concrete and retard the blockage of the pervious concrete.
本发明提供了一种抗裂防堵透水混凝土及其制备方法，原材料包括水泥，再生骨料，木质纤维，防堵剂，以及水，防堵剂中含有不定形高活性游离氧化硅和高吸附性能的材料，其制备步骤包括：步骤1：将园林废弃物干燥脱水得到产物一；步骤2：将所述产物一切块得到产物二；步骤3：将碎石和所述产物二混合后加入少量水进行搅拌，得到产物三；步骤4：将所述水泥，防堵剂和水加入所述产物三中进行搅拌，得到抗裂防堵透水混凝土。步骤5：将所述抗裂防堵透水混凝土铺设在地面上。本领域的技术人员致力于开发一种抗裂防堵透水混凝土及其制备方法，解决透水混凝土的“泛碱”和抵抗透水混凝土内部生物膜的形成，减缓透水混凝土的堵塞问题。
