Construction waste recycled aggregate and steel slag mixed high-strength concrete and preparation method thereof
The invention relates to the technical field of building materials, and discloses high-strength concrete with construction waste recycled aggregate mixed with steel slag and a preparation method of the high-strength concrete. After the construction waste recycled aggregate mixed with the steel slag is mixed with the steel slag, the performance indexes of the concrete reach high strength and excellent impermeability and freezing resistance, the compressive strength after standard curing can reach 85.7 MPa, and the flexural tensile strength reaches 8.9 MPa; the splitting strength reaches 4.6 MPa, and the compression elasticity modulus is larger than or equal to 46 GPa; the anti-permeability grade reaches P10 or above, and the number of quick freezing and thawing times reaches 270 or above. The construction waste recycled aggregate and the steel slag aggregate are directly recycled and utilized on a large scale, complex energy consumption processes such as grinding and washing are not needed, the appearance quality is not scumming or cracking, and the concrete becomes novel green high-performance concrete and can be widely applied to the fields of roads, municipal administration and water conservancy projects. The method is especially suitable for projects such as village reviving roads and various foundation beds.
本发明涉及建筑材料技术领域，且公开了一种建筑垃圾再生骨料混掺钢渣高强混凝土及其制备方法，本发明建筑垃圾再生骨料混掺钢渣后，混凝土性能指标达到高强、抗渗性、抗冻性优，标准养护后抗压强度即可达到85.7MPa，弯拉强度达到8.9MPa；劈裂强度达到4.6MPa，受压弹性模量≥46GPa；抗渗等级达P10以上，快速冻融次数达270次以上。实现了建筑垃圾再生骨料、钢渣骨料的直接资源化、规模化利用，无需粉磨、水洗等复杂耗能工艺，而且外观质量不泛霜、不开裂等，成为一种新型的绿色高性能混凝土，可广泛用于公路、市政、水利工程领域，尤其适合乡村振兴道路、各种基础垫层等项目。
