【摘要】：以膨脹珍珠巖作為基體材料吸附硬脂酸丁酯制備相變儲能骨料。對摻加不同摻量的相變儲能骨料和硅粉的混凝土進行了抗壓性能試驗研究。試驗結果表明,相變儲能骨料的摻加會導致混凝土的抗壓強度降低,當摻量為10%時,抗壓強度的降低幅度在10%的范圍內。硅粉的摻加能夠提高混凝土的抗壓強度,摻量在5%~10%時,抗壓強度至少提高22%。相變儲能骨料和硅粉復合摻加時,相變儲能骨料摻量為20%,硅粉摻量為5%時效果最好,抗壓強度與素混凝土的基本相同。
[Abstract]:The phase change energy storage aggregate was prepared by adsorption of butyl stearate with expanded perlite as matrix material. The compressive properties of concrete mixed with different amount of phase change energy storage aggregate and silica powder were studied. The addition of phase change energy storage aggregate will reduce the compressive strength of concrete. When the content is 10, the reduction range of compressive strength is in the range of 10%. The addition of silica powder can improve the compressive strength of concrete, and when the content is between 5 and 10, the compressive strength of concrete can be increased. The compressive strength is increased by at least 22. When the phase change energy storage aggregate and silica powder are mixed, the content of phase change energy storage aggregate is 20 and the silicon powder is 5. The compressive strength is basically the same as that of plain concrete.
