Environment-friendly regenerated brick and preparation process thereof
The invention relates to the field of regenerated bricks, and particularly discloses an environment-friendly regenerated brick and a preparation method thereof. The preparation method of the environment-friendly recycled brick comprises the following steps: step a, mixing Portland cement, water, nano silica fume and fatty alcohol-polyoxyethylene ether to form a prefabricated mixture, then infiltrating the prefabricated mixture into gaps of recycled aggregate, and mixing the prefabricated mixture with the filled recycled aggregate to obtain a mixture; step b, performing modification operation on silicon dioxide to obtain modified silicon dioxide; c, performing modification operation on the coconut shell fibers to obtain modified coconut shell fibers; step d, mixing the mixed material, the modified silicon dioxide and the modified coconut fiber, and standing, curing and forming to obtain the environment-friendly regenerated brick. The preparation method disclosed by the invention has the advantages that the environment-friendly recycled brick can completely utilize the recycled aggregate to replace natural aggregate, resources are saved, and the production cost is reduced.
本发明涉及再生砖领域，具体公开了一种环保再生砖及其制备方法。环保再生砖的制备方法包括以下步骤：步骤a，混合硅酸盐水泥、水、纳米微硅粉以及脂肪醇聚氧乙烯醚，形成预制混合料，再将预制混合料渗入再生骨料的缝隙中，并混合预制混合料以及经填充的再生骨料，得到拌和料；步骤b，对二氧化硅进行改性操作，得到改性二氧化硅；步骤c，对椰壳纤维进行改性操作，得到改性椰壳纤维；步骤d，混合拌和料、改性二氧化硅以及改性椰壳纤维，并静置养护成型，即得环保再生砖。本发明的制备方法具有使得环保再生砖可完全利用再生骨料替代天然骨料，有利于节约资源、降低生产成本的优点。
