Ultra-high performance concrete and preparation method thereof
The invention provides ultra-high performance concrete and a preparation method thereof, and relates to the technical field of concrete, the ultra-high performance concrete comprises the following components by weight: 600-800 parts of high alumina cement, 200-400 parts of a mineral admixture, 800-1100 parts of a high temperature resistant aggregate, 100-400 parts of a fiber material, 5-10 parts of a water reducer and 150-250 parts of water; the high-temperature-resistant aggregate comprises at least one of corundum, carborundum or silicon nitride ceramic; the fiber material comprises steel fibers and organic synthetic fibers; the mineral admixture is at least one of fly ash, slag powder, phosphorus slag powder, silica fume or metakaolin. By adopting a full-high-alumina cement system, stable C3A6H3 and Al (OH) 3 phases are formed, so that cement stone structure collapse is avoided. The technical problem that in the prior art, cement and aggregate components in conventional refractory concrete cannot adapt to heat loss impact caused by the high-temperature environment of 1500 DEG C or above is solved.
本发明提供了一种超高性能混凝土及其制备方法，涉及混凝土技术领域，包括以下重量份数的组分：600～800份的高铝水泥、200～400份的矿物掺合料、800～1100份的耐高温骨料、100～400份的纤维材料、5～10份的减水剂和150～250份的水；所述耐高温骨料包括刚玉、金刚砂或氮化硅陶瓷中的至少一种；所述纤维材料包括钢纤维和有机合成纤维；所述矿物掺合料为粉煤灰、矿渣粉、磷渣粉、微硅粉或偏高岭土中的至少一种。通过采用全高铝水泥体系，形成稳定的C3A6H3和Al(OH)3相，因而不会出现水泥石结构瓦解。解决了现有技术中常规耐火混凝土中的水泥和骨料组分适应不了1500℃以上高温环境带来的热损失冲击的技术问题。
