High-temperature-resistant high-performance concrete and preparation method thereof
The invention discloses high-temperature-resistant high-performance concrete and a preparation method thereof, and belongs to the technical field of concrete. The high-temperature-resistant high-performance concrete is prepared by adding steel fibers and polypropylene fibers into concrete, and specifically comprises the following raw materials in parts by mass: 171 parts of cement, 257 parts of fly ash, 42 parts of an expanding agent, 128 parts of river sand, 111.3 parts of water, 3.42 parts of a water reducing agent, 13.08-39.25 parts of steel fibers and 3.1 parts of polypropylene fibers. The prepared high-temperature-resistant high-performance concrete overcomes the defects that a traditional concrete material is low in bending strength and not resistant to high temperature; the high temperature resistance of the structure is enhanced; the residual mechanical property of the material is improved, the structure can still keep good integrity and residual mechanical property after a fire disaster, and the service life of the structure is effectively prolonged.
本发明公开了一种耐高温高性能混凝土及其制备方法，属于混凝土技术领域。所述耐高温高性能混凝土是在混凝土中添加钢纤维和聚丙烯纤维，具体包括以下质量份数的原料：171份水泥、257份粉煤灰、42份膨胀剂、128份河砂、111.3份水、3.42份减水剂、13.08‑39.25份钢纤维、3.1份聚丙烯纤维。本发明制备的耐高温高性能混凝土改善了传统混凝土材料所存在的抗弯强度低、不耐高温的缺陷；增强了结构的耐高温能力；提高了材料的残余力学性能，可实现结构在经历火灾后依然保留较好的完整性和残余力学性能，有效延长结构使用寿命。
