Green ultra-high performance concrete as well as preparation method and application thereof
The invention provides green ultra-high performance concrete and a preparation method and application thereof, and relates to the technical field of building materials, the green ultra-high performance concrete is mainly prepared from the following raw materials: 650-850 parts of cement, 100-140 parts of silica fume, 196-230 parts of water, 110-275 parts of rice hull ash, 110-195 parts of PAC water purifying agent waste residue, 1100-1200 parts of aggregate, 8.4-12.4 parts of a water reducing agent, 4.2-6 parts of a defoaming agent, and 142-174 parts of steel fiber. The technical problems of environmental pollution and resource waste caused by disordered discharge of the PAC water purifying agent waste residues and ecological environment deterioration and resource waste caused by large cement consumption in the ultra-high performance concrete in the prior art are solved, and efficient utilization of the PAC water purifying agent waste residues and the rice hull ash is achieved. The ultra-high performance concrete is low in energy consumption, low in carbon emission and low in cost, and the technical effects of excellent performance and small shrinkage of the concrete are ensured.
本发明提供了一种绿色超高性能混凝土及其制备方法、应用，涉及建筑材料的技术领域，主要由以下原料制备而成：水泥650‑850份、硅灰100‑140份、水196‑230份、稻壳灰110‑275份、PAC净水剂废渣110‑195份、集料1100‑1200份、减水剂8.4‑12.4份、消泡剂4.2‑6份，以及钢纤维142～174份，解决了PAC净水剂废渣无序排放所导致的环境污染和资源浪费，以及现有技术的超高性能混凝土中水泥用量大而导致的生态环境恶化和资源浪费的技术问题，达到了PAC净水剂废渣和稻壳灰的高效利用，使超高性能混凝土的能耗低、碳排放量低和成本低，以及保证了混凝土的性能出色和收缩小的技术效果。
