普通的混凝土在施工中经常出现温度裂缝和抗压强度有限的问题。为克服这一问题需要对相变材料的性能进行相应的研究。因此,本文通过在实验室内对相变材料的进行技术复合。通过对大体积的相变混凝土的内部温度场的模拟再现,自行设置一套个性化和匹配度更高的温度测试系统对其进行设计和控制,最后通过实测数据和实验情况,来展开研究、分析和对比。最终的实验结果展现出来的相变材料较于普通混凝土在控制和降低内部温升速度,降低温度变化的振幅上作用非常之大,值得推广使用。
Ordinary concrete often appear in the construction of temperature cracks and compressive strength of the limited problems. To overcome this problem, the properties of phase change materials need to be studied accordingly. Therefore, this article by phase transition in the laboratory technology composite materials. Through the simulation and reconstruction of the internal temperature field of the large-volume phase-change concrete, a set of personalized and higher-matching temperature test system is set up to design and control it. Finally, through the measured data and experimental conditions, Analysis and comparison. The final experimental results show that phase change materials play a very significant role in controlling and reducing the internal temperature rise and amplitude of temperature changes compared with ordinary concrete, which is worthy of wide application.
