Environment-friendly impervious concrete and preparation method thereof
The invention relates to environment-friendly impervious concrete and a preparation method thereof. The invention relates to environment-friendly impermeable concrete, which is prepared from the following components in parts by weight: 200 to 300 parts of cement; 500 to 600 parts of fine stone; 400 to 450 parts of sand; 100 to 150 parts of fly ash; 2 to 5 parts of an air entraining agent; 1.5 to 2.0 parts of an anti-permeability agent; and 200 to 500 parts of modified recycled aggregate. The modified recycled aggregate is prepared by the following steps: a, pretreatment: firstly, performing impurity removal, crushing and screening on waste concrete blocks, and then heating and stirring the waste concrete blocks and a pickling solution in vacuum to prepare the recycled aggregate; and b, modification treatment: heating and stirring the recycled aggregate and the modification liquid, freezing and drying, and crushing and screening to obtain the modified recycled aggregate. Modification liquid is prepared from modified sol and modified filler; and modification sol is prepared from nanoscale silicon dioxide sol, sodium methylsilanolate and triethanolamine. The concrete provided by the invention has the advantages of environmental protection and impermeability.
本申请涉及一种环保型抗渗混凝土及其制备方法。一种环保型抗渗混凝土，由如下重量份数的组分组成：水泥200‑300份；细石500‑600份；砂子400‑450份；粉煤灰100‑150份；引气剂2‑5份；抗渗剂1.5‑2.0份；改性再生骨料200‑500份；改性再生骨料由以下步骤制备获得：a、预处理：先将废旧混凝土块除杂、破碎、筛分后，与酸洗液在真空中加热搅拌，制得再生骨料；b、改性处理：先将再生骨料与改性液加热搅拌，再冷冻烘干，经破碎、筛分后，即可制得改性再生骨料；改性液由改性溶胶和改性填料组成；改性溶胶由纳米级二氧化硅溶胶、甲基硅醇钠和三乙醇胺组成。本申请的混凝土具有环保抗渗的优点。
