Modified recycled aggregate high-temperature-resistant ultrahigh-ductility concrete and preparation method thereof
The invention provides modified recycled aggregate high-temperature-resistant ultrahigh-ductility concrete and a preparation method thereof, and belongs to the technical field of cement-based building materials, the concrete is prepared from the following raw materials in parts by weight: 300-370 parts of cement, 340-420 parts of fly ash, 20-35 parts of dechlorinated fly ash, 600-720 parts of modified recycled coarse aggregate, 280-510 parts of quartz sand, 10-25 parts of polyethylene fiber and 0.5-1 part of multiwalled carbon nanotube. The concrete is prepared from the following components in parts by weight: 50-60 parts of calcium carbonate whiskers, 160-210 parts of water, 3-8 parts of polycarboxylate superplasticizer and 0.5-2 parts of thickener. By adopting the modified recycled aggregate high-temperature-resistant ultrahigh-ductility concrete and the preparation method thereof, the green and environment-friendly high-temperature-resistant ultrahigh-ductility concrete with excellent performance is prepared, and the reutilization of construction wastes and household wastes is realized.
本发明提供了一种改性再生骨料耐高温超高延性混凝土及其制备方法，属于水泥基建筑材料技术领域，该混凝土由以下重量份原料组成：水泥300~370份，粉煤灰340~420份，脱氯飞灰20~35份，改性再生粗骨料600~720份，石英砂280~510份，聚乙烯纤维10~25份，多壁碳纳米管0.5~1份，碳酸钙晶须50~60份，水160~210份，聚羧酸减水剂3~8份，增稠剂0.5~2份。本发明采用上述的一种改性再生骨料耐高温超高延性混凝土及其制备方法，制备了一种绿色环保、性能优异的耐高温超高延性混凝土，实现了建筑垃圾及生活垃圾的再利用。
