UHPC material and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a UHPC material and a preparation method thereof. The UHPC material disclosed by the invention is prepared from the following components in parts by weight: 668 to 674 parts of cement, 167 to 169 parts of fly ash, 113 to 115 parts of silica fume, 78 to 137 parts of steel fiber, 180 to 182 parts of water, 24 parts of an efficient polycarboxylate superplasticizer and 1210 to 1220 parts of sand. The steel fibers are steel fibers in recycled waste tires. The steel fibers adopted in the invention are extracted and recovered from waste tires, and the cost of the steel fibers is less than 20% of that of industrial steel fibers; the cement, the fly ash, the silica fume, the steel fiber, the water, the efficient polycarboxylic acid water reducer and the sand are scientifically proportioned, so that the prepared UHPC is excellent in compressive strength, tensile strength, crack resistance, toughness and working performance, and the cost is only 60% of that of the current commercial UHPC; according to the preparation method of the UHPC material, resource recycling is achieved, good economic, social and environmental benefits are achieved, and wide application prospects are achieved.
本发明属于建筑材料技术领域,具体涉及一种UHPC材料及其制备方法。本发明中的UHPC材料按重量份包括如下组分:水泥668‑674份、粉煤灰167‑169份、硅灰113‑115份、钢纤维78‑137份、水180‑182份、高效聚羧酸减水剂24份、砂子1210‑1220份;钢纤维采用回收废旧轮胎中的钢纤维。本发明中采用的钢纤从废旧轮胎中提取回收,其成本不到工业钢纤维的20%;将水泥、粉煤灰、硅灰、钢纤维、水、高效聚羧酸减水剂和砂子按照科学的配比,使制得UHPC的抗压强度、抗拉强度、抗裂性能、韧性和工作性能优良,且成本仅为目前商品UHPC的60%;本发明的UHPC材料制备方法,实现了资源再生利用,具有较好的经济、社会和环境效益,且具有广阔的应用前景。
