Pavement concrete structure for deicing and preparation method thereof
The invention discloses a pavement concrete structure for deicing and a preparation method thereof. The pavement concrete structure comprises wave-absorbing concrete, the wave-absorbing concrete comprises cement, sand, stone, graphite powder and steel fiber according to a mixing ratio of (0.9-1.1):(1.83-1.87):(3.53-3.58):(0.03-0.05):(0.07-0.11), and the water cement ratio is 0.51-0.55. The steel fiber and the graphite powder are doped into the cement, the sand and the stone, the steel fiber is a magnetic loss type material, and the graphite is an electric loss type material, so that the concrete structure has very good wave-absorbing performance, and the doping of the steel fiber not only can improve the flexural tensile strength of the concrete, but also can play roles in toughening and crack resistance. The graphite and the steel fiber are doped in the concrete, and the graphite and the steel fiber are large in surface area, high in water consumption and not involved in cement hydration as powder, so that the surface laitance of the concrete after vibration is less, the formed surface is rough, construction depth is high and skid resistance is good.
本发明公开了一种用于除冰的路面混凝土结构及其制备方法，包括吸波混凝土，所述吸波混凝土的成分配合比包括：水泥：砂子：石子：石墨粉：钢纤维＝0.9～1.1：1.83～1.87：3.53～3.58：0.03～0.05：0.07～0.11，水灰比为0.51～0.55。在水泥、砂子和石子中掺入钢纤维和石墨粉，钢纤维是磁损耗型材料，而石墨是电损耗型材料，使本发明的混凝土结构具有非常好的吸波性能，并且钢纤维的掺入不仅可以混凝土的抗弯拉强度，还可以起到增韧阻裂的作用，而且在混凝土中掺加石墨和钢纤维，由于其作为粉料表面积较大，消耗水分较多且不参与水泥水化，导致混凝土振捣后表面浮浆较少，因此成型后表面粗糙、构造深度较大，抗滑性能好。
