Description

Energy storage deicing building block brick based on industrial waste Technical Field The invention belongs to the technical field of functional building materials, and particularly relates to an energy-storage deicing block brick based on industrial waste. Background Under cold and frozen environment, areas such as a pavement, a tunnel portal, an outer surface of a building and the like are easy to generate ice formation and ice coating, and an ice layer not only reduces the road adhesion coefficient and induces safety accidents such as skidding of pedestrians and vehicles, but also can cause blockage of bridge deck expansion joints, drainage structures and the like, so that frost heaving damage and service performance decline are caused, and frequent emergency treatment and high operation and maintenance cost are brought. The existing deicing mode mainly comprises mechanical deicing, snow-melting agent spreading, external heating/electric heating deicing and the like, and the mechanical deicing can rapidly remove the surface ice and snow, but has the problems of easiness in scraping damage to a road surface and a waterproof layer, limited efficiency and easiness in repeated icing. The snow-melting agent depends on a chemical freezing point depression mechanism, can cause concrete salt damage and secondary environmental pollution after long-term use, and has obvious effect attenuation under low-temperature extreme working conditions. The external heating/electric heating deicing can realize active deicing, but usually an independent heating cable or power supply facility is required to be laid, the system has complex structure and high energy consumption, and the problems of local overheating, line failure, difficult maintenance and the like are easy to occur. More importantly, the existing scheme is to design the structural materials and the energy supply/deicing system in a cutting way, deicing facilities are often externally arranged or attached as later-stage additional components, durability, maintainability and cost controllability are difficult to achieve in a large-area pavement scene, and a core bottleneck-unstable energy source, low system integration and insufficient long-term service reliability of the deicing engineering in a cold area are formed. A large amount of fly ash/fly ash generated in industries such as thermal power, metallurgy and the like belongs to typical industrial waste, and if improperly disposed, the environment risks such as land occupation, dust diffusion and the like can be caused. The alkali-activated cementing material based on the fly ash/fly ash provides a low-carbon potential path for recycling the solid waste, but most of the existing fly ash-based block bricks are focused on bearing, heat preservation or durable modification and still stay on the single functional layer of 'structural materials'. Even if a small amount of researches are tried to endow the fly ash-based block brick with conductive or thermal management capability, the fly ash-based block brick is realized by externally doping conductive filler or externally attaching a heating layer, and the problems of discontinuous conductive network, interface stripping, performance drift under wet freeze thawing, easy damage of an external cable and the like exist, so that the long-term stable operation requirement under the environment of repeated freeze thawing and load superposition in cold regions is difficult to meet. Therefore, a novel functional building material for cold region engineering application is needed, and on the premise of not remarkably increasing construction complexity, the problems of easy damage and difficult maintenance of an external system are solved by deeply coupling the high-valued utilization of industrial wastes with the energy storage deicing function and through structural packaging and reliable electric connection. Disclosure of Invention Aiming at the problems, the invention provides an energy-storage deicing block brick based on industrial waste, which takes fly ash as a main solid raw material, adopts an alkali excitation system compounded by sodium hydroxide solution and sodium silicate solution to prepare a formed brick body substrate, integrates a capacitor array formed by fly ash-based electrodes and gel electrolyte in a cavity of the brick body substrate, realizes energy storage and deicing application of the block brick, and gives consideration to solid waste recycling and low-carbon sustainable properties. The invention particularly relates to an energy-storage deicing building block brick based on industrial waste, which comprises a cavity brick body, a brick cover arranged at the top of the cavity brick body and a capacitor array arranged in a cavity of the cavity brick body, wherein the cavity brick body is of a cuboid hollow structure, the top of the cavity brick body is open, a cuboid cavity is arranged in the cavity brick body, the brick cover is a rectangular co
