High-toughness comb plate expansion joint filling concrete
The invention discloses high-toughness comb plate expansion joint filling concrete which is prepared from the following raw materials in parts by weight: 10-20 parts of cement, 5-10 parts of water, 18-36 parts of sand, 37-74 parts of stones, 0.15-0.3 part of aluminum alloy fibers, 0.1-0.2 part of carbon fibers and 0.2-0.4 part of an additive, gaps among the stones can be filled when the stones are mixed and stirred, the gaps after concrete mixing are reduced, the density of the concrete is improved, and the service life of the concrete is prolonged. The tensile elongation of the aluminum alloy fibers and the tensile strength of the carbon fibers can improve the tensile strength and the torsional strength of the concrete, and the phenomenon that the concrete is broken when the comb plate is extruded by a vehicle during later use is reduced.
本发明公开了一种高韧性梳齿板伸缩缝填充混凝土，其原料包含以下重量份的组分：水泥10～20份、水5～10份、砂18～36份、石子37～74份、铝合金纤维0.15～0.3份、碳纤维0.1～0.2份和添加剂0.2～0.4份，可对砂石在混合搅拌时之间的间隙进行填充，降低混凝土混合后的间隙提高混凝土的密度，铝合金纤维的抗拉伸展率和碳纤维的抗拉伸强度，即可提高混凝土的抗拉和抗扭强度，降低后期使用时梳齿板在受到车辆的挤压，混凝土出现破裂的现象。
