High-ductility modified cement
The invention provides high-ductility modified cement and a preparation method thereof, and relates to high-ductility modified cement. The high-ductility modified cement comprises the following raw materials: cement, fly ash, modified starch, polyvinyl alcohol fiber, silicon powder, water, rubber powder, a water reducing agent and the like. By adding the rubber powder, the modified starch and the polyvinyl alcohol fibers with different lengths, the ductility of the modified cement is improved, and meanwhile, the low-temperature resistance of the modified cement is improved.
本发明提供了一种高延性改性水泥及其制备方法，涉及一种高延性改性水泥。本发明的高延性改性水泥包括水泥，粉煤灰，改性淀粉，聚乙烯醇纤维，硅粉，水，橡胶粉，减水剂等原料。本发明通过橡胶粉、改性淀粉、不同长度聚乙烯醇纤维的添加，在提高改性水泥延性的同时提高了其耐低温性能。
