Freeze-thaw-resistant foam concrete for high-cold and high-altitude areas and preparation method thereof
The invention discloses freeze-thaw-resistant foam concrete for high-cold and high-altitude areas and a preparation method of the freeze-thaw-resistant foam concrete, and belongs to the technical field of building material concrete. The freeze-thaw-resistant foam concrete comprises the following raw materials: 32-38 wt% of cement, 13-19 wt% of ceramsite, 20-26 wt% of fine aggregate, 6-11 wt% of fibers, 7-13 wt% of fly ash, 4-8 wt% of silica powder and 3 wt% of an additive; wherein the ceramsite is prepared by sintering steel slag powder, regenerated building micro powder, waste plant fiber powder, steel fibers or basalt fibers by adopting a special method. The freeze-thaw resistant foam concrete provided by the invention has the performance advantages of light weight and high strength, and can meet various performance requirements of high-cold and high-altitude areas; the thermal insulation performance and the workability are good, and the concrete can better adapt to severe construction environments in high-cold and high-altitude areas.
本发明公开一种用于高寒高海拔地区的抗冻融泡沫混凝土及其制备方法，属于建筑材料混凝土技术领域，其原料包括水泥32‑38wt％、陶粒13‑19wt％、细骨料20‑26wt％、纤维6‑11wt％、粉煤灰7‑13wt％、硅微粉4‑8wt％、外加剂3wt％；其中，陶粒是用钢渣粉、再生建筑微粉、废弃植物纤维粉、钢纤维或玄武岩纤维采用特殊方法烧结制备而成。本发明提供的抗冻融泡沫混凝土，具有轻质高强的性能优势，能满足高寒高海拔地区的各种性能要求；保温隔热，和易性好，更能适应高寒高海拔地区的严峻的施工环境。
