Temperature-control phase-change aggregate as well as preparation method and application thereof
The invention discloses a temperature-control phase-change aggregate and a preparation method and application thereof, the preparation method comprises the following steps: (1) drying ceramsite, removing slag and breaking shells, and then placing the ceramsite in molten paraffin for vacuum adsorption to obtain the phase-change aggregate; and (2) sequentially carrying out water cooling treatment and airing treatment on the phase-change aggregate obtained in the step (1), and finally wrapping and packaging the phase-change aggregate by adopting superfine cement or epoxy resin to obtain the phase-change aggregate. The preparation method disclosed by the invention is simple and convenient, rich in raw materials, low in price, suitable for large-scale production and application and wide in market prospect, and the prepared temperature-control phase-change aggregate selects superfine cement or epoxy resin as an aggregate shell, so that paraffin in the aggregate can stably exist when the temperature is increased; therefore, the temperature rise of hydration heat of the mass concrete is effectively controlled, the temperature stress of the mass concrete is reduced, the occurrence of temperature cracks is reduced, and the stability of a concrete structure is improved.
本发明公开了一种温控相变骨料及其制备方法与应用，其制备方法包括以下步骤：(1)将陶粒烘干后去渣破壳，然后置于熔融石蜡内进行真空吸附，得到相变骨料；(2)将步骤(1)得到的相变骨料依次进行水冷处理、晾晒处理，最后采用超细水泥或环氧树脂对相变骨料进行包裹封装，制得。本发明制备方法简便，原料丰富，价格低廉，适于大规模生产应用，有广阔的市场前景，制得的温控相变骨料选用超细水泥或环氧树脂作为骨料外壳，可以保障骨料内部的石蜡在温度升高时能稳定存在，从而有效的控制大体积混凝土水化热的温升，减少大体积混凝土的温度应力，减少温度裂缝的出现，提高混凝土结构的稳定性。
