Phase-change mass concrete and preparation method thereof
The invention discloses phase-change mass concrete which comprises the following components: 140-170kg/m < 3 > of water; 300-400 kg/m < 3 > of cement; 50-150 kg/m < 3 > of coal ash; 650-850 kg/m < 3 > of fine aggregate; 1000-1200 kg/m < 3 > of coarse aggregate; 9.0-13.6 kg/m < 3 > of water reducing agent; 1-5 kg/m < 3 > of a phase change material; the phase-change material is a high-thermal-conductivity nanoscale microcapsule phase-change material, and the phase-change temperature is 49 DEG C; the phase-change mass concrete prepared based on the phase-change material can effectively slow down the internal temperature rise of the mass concrete, reduce the temperature gradient and reduce the probability of temperature cracks of the mass concrete; and compared with a traditional mass concrete cooling method, the construction cost is greatly reduced, the process is simple, the performance is stable, a traditional cooling water pipe cooling method can be replaced, and the construction period is greatly shortened.
本发明公开了一种相变大体积混凝土，组成为水：140～170kg/m3；水泥：300～400kg/m3；粉煤灰：50～150kg/m3；细集料：650～850kg/m3；粗集料1000～1200kg/m3；减水剂：9.0～13.6kg/m3；相变材料：1～5kg/m3；所述的相变材料是高导热纳米级微胶囊相变材料，相变温度49℃；本发明所提供的基于相变材料制备的相变大体积混凝土可有效减缓大体积混凝土内部温升，降低温度梯度，减小大体积混凝土温度裂缝发生的几率；相较于传统大体积混凝土降温方法大大降低施工成本，具有工序简单，性能稳定，可替代传统的冷却水管降温方法，大大减少工期。
