Ultrahigh-ductility high-temperature-resistant coal gangue concrete and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to ultrahigh-ductility high-temperature-resistant coal gangue concrete and a preparation method thereof.Recycled coal gangue is treated through a thermal activation technology, fibers are mixed, and then modified calcium carbonate whiskers are used for enhancing the high-temperature resistance of the concrete; and polyethylene glycol methacrylate and a thickening agent are adopted to ensure the concrete workability of the modified coal gangue and the machine-made sand as aggregates, so that the green, low-carbon, high-temperature-resistant and high-ductility coal gangue concrete is prepared, and popularization and application of the coal gangue concrete in building structures are facilitated.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种超高延性耐高温煤矸石混凝土及其制备方法，通过热活化技术处理回收的煤矸石，混掺入纤维，再利用改性碳酸钙晶须增强其耐高温性能，并采用聚乙二醇甲基丙烯酸酯和增稠剂保证改性煤矸石和机制砂作为骨料的混凝土和易性，制备一种绿色低碳、耐高温的高延性煤矸石混凝土，有利于煤矸石混凝土在建筑结构中的推广使用。
