Coarse aggregate ultra-high performance concrete with standard curing strength exceeding 160MPa
The invention discloses coarse aggregate ultra-high performance concrete with the standard curing strength exceeding 160 MPa, and belongs to the technical field of building materials, the ultra-high performance concrete comprises the following components in parts by weight: 627-847 parts of cement, 308-363 parts of a composite admixture, 554.7-706.6 parts of fine aggregate, 471.0-600.1 parts of coarse aggregate, 9.0-16.0 parts of a water reducing agent, 143.0-176.0 parts of water, and steel fibers accounting for 2.4-2.8% of the volume of the ultra-high performance concrete. The prepared coarse-aggregate ultra-high-performance concrete is high in adaptability and good in workability, the 28d standard curing strength of the coarse-aggregate ultra-high-performance concrete exceeds 160MPa, and the coarse-aggregate ultra-high-performance concrete can meet most coarse-aggregate-containing ultra-high-performance concrete projects which can reach the strength index only through steam curing.
本发明公开了一种标准养护强度超过160MPa的粗骨料超高性能混凝土，属于建筑材料技术领域，该超高性能混凝土按重量份包括：水泥627～847份、复合掺合料308～363份、细骨料554.7～706.6份、粗骨料471.0～600.1份、减水剂9.0～16.0份、水143.0～176.0份，以及占超高性能混凝土体积掺量2.4～2.8％的钢纤维。本发明所制得的粗骨料超高性能混凝土适配性强，具有良好的工作性，其28d标准养护强度超过160MPa，能够满足大多数需蒸汽养护才能达到强度指标的含粗骨料超高性能混凝土工程。
