Concrete admixture and preparation method thereof
The invention relates to a concrete admixture and a preparation method thereof, and belongs to the technical field of concrete preparation. The preparation method comprises the following steps: firstly, taking sweet potatoes as a raw material, crushing the raw material, carrying out homogenization treatment, then filtering to remove sweet potato filter residues, standing and precipitating the filtrate to obtain a sweet potato starch precipitate, then taking pineapples, grapes and pigskin as raw materials, grinding the raw materials, performing sealing fermentation to obtain a modifying solution, mixing the modifying solution with the sweet potato starch for modification to obtain modified sweet potato starch, mixing and reacting the modified sweet potato starch with epoxy chloropropane, and performing vacuum freeze drying to finally obtain the concrete admixture. The concrete admixture is high in compressive strength, low in bleeding rate and wide in application prospect.
本发明涉及一种混凝土外加剂及其制备方法，属于混凝土制备技术领域。本发明首先以红薯为原料，将其粉碎后均质处理，之后过滤去除红薯滤渣，并将滤液静置沉淀，得到红薯淀粉沉淀，接着以凤梨、葡萄和猪皮为原料，将其研磨后密封发酵，得到改性液，最后将改性液和红薯淀粉混合改性，得到改性红薯淀粉，再将改性红薯淀粉和环氧氯丙烷混合反应后真空冷冻干燥，最终制得混凝土外加剂，本发明制得混凝土外加剂抗压强度高，泌水率低，具有广阔的应用前景。
