Renewable high-strength concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses renewable high-strength concrete and a preparation method thereof. The preparation method of the renewable high-strength concrete comprises the following steps: step 1, pretreating recycled aggregate, specifically comprising the following steps: step 1-1, mixing magnet powder and water to form a pretreatment solution; step 1-2, immersing the recycled aggregate with the pretreatment liquid; step 1-3, pressurizing; step 1-4, immersing the recycled aggregate in the gap filling liquid; and step 1-5, pressurizing and applying a magnetic field to obtain the regenerated filling aggregate. The gap filling liquid consists of the following components: liquid sodium silicate; magnet powder; a water-absorbent resin powder; hollow glass beads; white carbon black; diatomite; step 2, preparing a concrete mixture; and step 3, curing and forming. The strength performance of the concrete prepared by the invention is not easily influenced by the recycled aggregate.
本发明涉及混凝土领域，具体公开了一种可再生高强度混凝土及其制备方法。其中，可再生高强度混凝土的制备方法包括以下步骤：步骤1，预处理再生骨料，具体如下：步骤1‑1，混合磁铁粉以及水，形成预处理液；步骤1‑2，用预处理液浸没再生骨料；步骤1‑3，加压；步骤1‑4，用缝隙填充液浸没再生骨料；步骤1‑5，加压、加磁场处理，即得到再生填充骨料；缝隙填充液由以下组分组成：液体硅酸钠；磁铁粉；吸水树脂粉末；空心玻璃微珠；白炭黑；硅藻土；步骤2，制备混凝土拌合料；步骤3，养护成型。本发明制得的混凝土的强度性能不容易受到再生骨料的影响的优点。
