Composite phase change aggregate, concrete and preparation method thereof
The invention discloses a composite phase change aggregate, concrete and a preparation method thereof, the composite phase change aggregate comprises at least three alkane phase change aggregates, and the alkane phase change aggregates can be a combination of dodecane aggregate, tridecane aggregate or tetradecane aggregate. The dodecane aggregate, the tridecane aggregate and the tetradecane aggregate are combined to respectively obtain the composite alkane phase-change aggregate, the upper limit and the lower limit of the phase-change temperature are adjusted, so that the phase-change temperature just meets the requirements of a low-temperature phase-change heat storage material at present, latent heat can be gradually released at the temperature, concrete is prevented from being excessively low in temperature, and the thermal performance of the concrete is improved; the heat influence on the soil is reduced, so that the influence of low-temperature frost heaving on a building structure is relieved.
本发明公开一种复合相变骨料、混凝土及其制备方法，所述复合相变骨料包括至少三种烷烃相变骨料，其中，多种烷烃相变骨料可以是十二烷骨料、十三烷骨料或十四烷骨料的组合，通过将十二烷骨料、十三烷骨料和十四烷骨料进行组合分别获得复合烷烃相变骨料，调节了相变温度的上下限，使之正好符合目前低温的相变蓄热材料的要求，在此温度下能逐渐释放潜热，防止混凝土过度低温，改善混凝土的热性能，降低对土壤的热影响，从而起到缓解低温冻胀对于建筑结构的影响。
