Energy storage phase change concrete and preparation method thereof
The invention discloses energy-storage phase-change concrete and a preparation method thereof, and relates to the technical field of building materials, the energy-storage phase-change concrete comprises the following raw materials: a cement base material, sand, aggregate, a water reducing agent and water; wherein the cement base material comprises cement, fly ash and rice hull ash, and the aggregate comprises phase change aggregate. The rice hull ash is added into a cement matrix material of the phase change concrete, and the interior of the rice hull ash has very high porosity and relatively high specific surface area, so that the rice hull ash has very good heat preservation and heat insulation performance. Therefore, after the phase change aggregate is introduced into the rice hull ash and fly ash doped cement matrix, the obtained rice hull ash-fly ash-phase change aggregate concrete can simultaneously utilize the latent heat of the phase change energy storage aggregate and the sensible heat of the rice hull ash-fly ash cement matrix to improve the heat insulation performance of the concrete in winter. Therefore, the energy storage phase change concrete provided by the invention can improve the heat insulation performance, so that the lowest indoor temperature in winter is improved, and the energy consumption related to heating is reduced.
本发明公开一种储能相变混凝土及其制备方法，涉及建筑材料技术领域，所述储能相变混凝土包括以下原料：水泥基材、砂、骨料、减水剂以及水；其中，所述水泥基材包括水泥、粉煤灰以及稻壳灰，所述骨料包括相变骨料。在相变混凝土的水泥基体材料中加入稻壳灰，稻壳灰内部具有很高的孔隙率以及较高的比表面积，使得稻壳灰具有很好的保温隔热性能。因此本申请中稻壳灰和粉煤灰掺杂的水泥基体，在引入相变骨料后，得到的稻壳灰‑粉煤灰‑相变骨料混凝土能够同时利用相变储能骨料的潜热和稻壳灰‑粉煤灰水泥基体的显热来提高混凝土的冬季隔热性能。因此本发明提供的储能相变混凝土能够提高隔热性能，从而提高冬季室内最低温度，减少与供暖相关的能耗。
