Concrete with high tensile strength and ultra-high performance and preparation method thereof
The invention relates to concrete with high tensile strength and ultra-high performance and a preparation method thereof, and belongs to the technical field of building materials. The ultra-high performance concrete is prepared from the following components in parts by weight: 500 to 800 parts of cement, 50 to 300 parts of silica fume, 70 to 200 parts of fly ash, 1000 to 1500 parts of fine aggregate, 8 to 10 parts of water reducing agent, 150 to 250 parts of water, 100 to 250 parts of steel fiber, 0.01 to 4 parts of graphene oxide, 70 to 260 parts of epoxy resin and 20 to 60 parts of curing agent, the tensile strength of the high-tensile-strength ultra-high-performance concrete can reach 10.3-14.1 MPa, the compressive strength can reach 160.7-178.2 MPa, and the high-tensile-strength ultra-high-performance concrete is widely suitable for application scenes with high tensile requirements such as large-span main bridge midspan bridge deck slabs and large-span floor slabs.
本发明涉及一种高抗拉强度超高性能混凝土及其制备方法，属于建筑材料技术领域。所述超高性能混凝土各组分及其重量份数如下：水泥500～800份，硅灰50～300份，粉煤灰70～200份，细骨料1000～1500份，减水剂8～10份，水150～250份，钢纤维100～250份，氧化石墨烯0.01～4份、环氧树脂70～260份、固化剂20～60份；所述高抗拉强度超高性能混凝土的抗拉强度可达10.3～14.1MPa，抗压强度可达160.7～178.2MPa，广泛适用于大跨度主桥跨中桥面板、大跨度楼板等抗拉要求高的应用场景中。
