Combined structure kerb and preparation method thereof
The invention discloses a combined structure kerb and a preparation method thereof, the combined structure kerb comprises an outer structure layer and an inner filling layer, the outer structure layer is C60-C80 ultra-high performance concrete, and black rice stone is used for replacing part of coarse aggregate according to the proportion of 40%-100% to obtain an imitated natural stone texture outer surface; and the inner filling layeris prepared from C20-C30 micro-expansion concrete with the free expansion rate of 0.010%-0.015% in 28d in air by replacing natural coarse aggregate with building solid waste recycled coarse aggregate according to the proportion of 20%-60%. The composite structure kerb prepared by the method can replace the traditional natural stone kerb, the traditional natural coarse aggregate is replaced by the building solid waste recycled coarse aggregate, the composite structure kerb is green and environment-friendly, and the composite structure kerb has good mechanical properties while achieving the effect of imitating the natural stone texture on the outer surface.
本发明公开了一种组合结构路缘石及其制备方法，组合结构路缘石包括外结构层和内填充层，所述外结构层为C60～C80的超高性能混凝土，通过将黑米石按比例40%～100%替代部分粗骨料得到仿天然石材纹理外表面；所述内填充层为C20～C30、空气中28d自由膨胀率0.010%～0.015%的微膨胀混凝土，利用建筑固废再生粗骨料按比例20%～60%替代天然粗骨料制得。本发明方法所制得的一种组合结构路缘石可替代传统天然石材路缘石，利用建筑固废再生粗骨料替代传统的天然粗骨料，绿色环保，在实现外表面仿天然石材纹理效果的同时还具备良好的力学性能。
