Steel slag concrete for reinforcing roadbed and preparation method thereof
The present invention discloses a steel slag concrete for reinforcing a roadbed and a preparation method thereof, the utilization rate of granulated blast-furnace slag powder is increased and the environmental burden is relieved through effective proportioning of fine steel slag and coarse steel slag, and according to GB28635-2012 concrete pavement brick measurement, the 7d compressive strength of the steel slag concrete for reinforcing the roadbed is 24.6-25.7 MPa. The invention also discloses processing equipment. According to the processing equipment, the mashing rods on the two sides are used for repeatedly mashing concrete aggregate, the whole mashing structure is ingenious, the crushing and mixing effects of the concrete aggregate are effectively improved, and the design of the conveying pipeline can help the concrete aggregate to be conveyed; and meanwhile, the concrete aggregate can be refined and mixed again in cooperation with the conveying screw rod, Portland cement and mineral powder enter the secondary treatment chamber through the discharging holes in the stirring pipe, and it is guaranteed that the Portland cement and the mineral powder are more dispersed and easier to mix.
本发明公开一种用于加固路基的钢渣砼及其制备方法，通过细钢渣与粗钢渣的有效配比，提高了粒化高炉矿渣粉的利用率，减轻了环境负担，根据GB28635‑2012混凝土路面砖测定，该用于加固路基的钢渣砼7d抗压强度为24.6‑25.7MPa，本发明同时公开一种加工设备，该加工设备通过两侧的捣碎杆反复对混泥土骨料进行捣碎处理，整个捣碎结构巧妙，有效提高混泥土骨料的粉碎与混合效果，输送管道的设计不仅可以帮助混泥土骨料进行输送，同时可以配合输送螺杆对混泥土骨料进行再次的细化与混合，硅酸盐水泥与矿粉通过搅拌管上的出料孔进入二级处理室内，保证硅酸盐水泥与矿粉更加分散，更易于混合。
