Microbial erosion resistant protective concrete and preparation method thereof
The invention discloses a microbial erosion resistant protective concrete, which comprises the following components by weight: 260-300 parts of cement, 80-120 parts of fly ash, 20-30 parts of silica fume, 40-60 parts of mineral powder, 930-960 parts of gravels, 720-750 parts of yellow sand, 8-12 parts of hydrated oxide, 8-12 parts of an additive, 40-64 parts of nano silicon dioxide, 2-4 parts of ahydrophobic poreblocking ingredient and 130-150 parts of water. The prepared concrete has excellent mechanical properties and volume stability, can effectively resist microbial erosion for a long time under the condition that no antibacterial component is added, and is particularly suitable for urban drainage pipelines, sewage treatment systems and the like.
本发明公开了一种耐微生物侵蚀防护混凝土，其组成按重量份数计如下：水泥260‑300份、粉煤灰80‑120份、硅灰20‑30份、矿粉40‑60份、碎石930‑960份、黄砂720‑750份、水合氧化物8‑12份、外加剂8‑12份、纳米二氧化硅40‑64份、疏水化合孔栓物2‑4份、水130‑150份。本发明制备的混凝土具有优异的机械性能和体积稳定性，在未添加抗菌组分的情况下能长时间有效抵抗微生物侵蚀，特别适用于城市排水管道和污水处理等系统。
