Regenerated red brick coarse aggregate large-flow-state concrete as well as preparation method and application thereof
The invention relates to recycled red brick coarse aggregate large-flow-state concrete as well as a preparation method and application thereof. The recycled red brick coarse aggregate large-flow-state concrete comprises the following components in parts by weight: 50-100 parts of cement, 580-600 parts of recycled brick and tile coarse aggregate, 700-760 parts of recycled machine-made sand, 160-200 parts of stone powder, 90-130 parts of fly ash, 7-10 parts of a modifier and 180-250 parts of water. According to the invention, the recycled brick and tile coarse aggregate is used for completely replacing pebbles, so that the obtained large-flow-state concrete achieves the effects of vibration-free and self-compaction, and can be suitable for parts with lower strength requirements, such as pavement base layers and subbase layers, thereby solving the problem that the construction cost is low in the construction process of roads, buildings and the like. The problem that equipment such as a large road roller needed for compacting plain soil, gravel and cement stabilized macadam contradicts with narrow space of a working platform is solved, and the purposes of saving resources and recycling waste are achieved.
本发明涉及一种再生红砖粗骨料大流态混凝土及其制备方法与应用，包括如下组分：水泥50～100重量份、再生砖瓦类粗骨料580～600重量份、再生机制砂700～760重量份、石粉160～200重量份、粉煤灰90～130重量份、改性剂7～10重量份、水180～250重量份。本发明将再生砖瓦类粗骨料100％替代石子，得到的大流态混凝土达到了免振捣、自密实的效果，可适用于路面基层、底基层等强度要求较低的部位，从而解决了道路、楼房等施工过程中，素土、砾石、水泥稳定碎石压实所需的大型压路机等设备与作业平台空间狭小相矛盾的问题，并达到节约资源、废物循环利用的目的。
