Low-carbon green ultra-high performance concrete and preparation method thereof
The invention provides low-carbon green ultra-high performance concrete and a preparation method thereof, and relates to the technical field of building materials. The low-carbon green ultra-high performance concrete provided by the invention is prepared from the following preparation raw materials in parts by weight: 550 to 650 parts of cement, 250 to 350 parts of regenerated red brick powder, 100 to 200 parts of fly ash, 90 to 110 parts of silica fume, 550 to 650 parts of natural sand, 450 to 550 parts of regenerated red brick sand, 40 to 50 parts of an additive, 160 to 180 parts of steel fiber and 170 to 190 parts of water. The problems of stacking and discarding of the construction waste red bricks are solved, the waste red bricks are subjected to processing of the regenerated red brick powder and the regenerated red brick sand, the problem of resource utilization is solved, and environmental protection benefits are improved. Meanwhile, the problems that existing ultra-high performance concrete is large in shrinkage, high in energy consumption, high in cost and poor in environmental protection property are solved.
本发明提供了一种低碳绿色超高性能混凝土及其制备方法，涉及建筑材料技术领域。本发明提供的低碳绿色超高性能混凝土，以重量份数计，包括以下制备原料：水泥550～650份、再生红砖粉250～350份、粉煤灰100～200份、硅灰90～110份、天然砂550～650份、再生红砖砂450～550份、外加剂40～50份、钢纤维160～180份、水170～190份。本发明解决了建筑垃圾红砖的堆置、废弃问题，将废弃红砖进行了再生红砖粉和再生红砖砂的加工，解决了资源利用的问题，提升了环境保护效益。同时，本发明解决了现有超高性能混凝土收缩大、高能耗、高成本、环保性差的难题。
