High-specific-strength lightweight high-strength concrete and preparation method thereof
According to the high-specific-strength light-weight high-strength concrete and the preparation method thereof, through reasonable raw material selection and mix proportion design, the double characteristics of light weight and high strength are achieved, the concrete has the compressive strength of 126.7-128.8 MPa and the density of 1805-1812 kg/m < 3 >, the specific strength exceeds 70 MPa/(t/m < 3 >), and the concrete is remarkably superior to traditional light-weight concrete. According to the invention, the fly ash floating beads are used as a key raw material, and through careful use amount design and cooperation with the hollow glass beads, an extremely low water-binder ratio and a high lightweight aggregate ratio are realized, and good working performance of the concrete is ensured. Besides, the concrete disclosed by the invention is simple in preparation method, easy for large-scale production, wide in raw material source and beneficial to cyclic utilization of resources, and conforms to the concepts of energy conservation, emission reduction and environmental protection. The high-specific-strength light-weight high-strength concrete is particularly suitable for projects with high requirements on self weight and strength, such as high-rise buildings and long-span bridges, and has a wide market application prospect.
本发明提供了一种高比强度的轻质高强混凝土及其制备方法，本发明的混凝土通过合理的原材料选择和配合比设计，实现了轻质和高强的双重特性，该混凝土具有126.7‑128.8MPa的抗压强度和1805‑1812kg/m3的密度，比强度超过70MPa/(t/m3)，显著优于传统轻质混凝土。本发明利用粉煤灰漂珠作为关键原材料，通过精心的用量设计，配合空心玻璃微珠，以实现极低的水胶比和较高的轻骨料比例，并保证混凝土良好的工作性能。此外，本发明的混凝土制备方法简单，易于大规模生产，且原材料来源广泛，有利于资源的循环利用，符合节能减排和绿色环保理念。本发明的高比强度轻质高强混凝土特别适用于对自重和强度要求较高的工程，如高层建筑、大跨度桥梁等，具有广阔的市场应用前景。
