Cement-based composite material, preparation method thereof and floating slab
The invention discloses a cement-based composite material, a preparation method thereof and a floating slab. The cement-based composite material comprises a base material, wherein the base material comprises Portland cement, silica fume, mineral powder, fly ash, quartz sand, water and a water reducing agent; a shape memory alloy; and a synthetic fiber. The cement-based composite material can improve the strength and toughness of joint areas among a plurality of plates forming the floating slab and greatly reduce the connecting length, so that the long floating slab can be applied to rail traffic engineering, the problems of an existing floating slab rail structure are solved, and the durability and comfort of the floating slab are greatly improved.
本公开揭示一种水泥基复合材料及其制备方法、浮置板。所述水泥基复合材料包括：基体材料，所述基体材料包括硅酸盐水泥、硅灰、矿粉、粉煤灰、石英砂、水和减水剂；形状记忆合金；以及合成纤维。该水泥基复合材料可以提高组成浮置板的多个板件之间接缝区域的强度和韧性，并大幅度降低连接长度，从而使长型的浮置板可以应用于轨道交通工程中，以此克服现有浮置板轨道结构存在问题，大幅度提高浮置板的耐久性和舒适性。
