摘要
为制备具有一定强度的掺料相变混凝土,通过分别对不同标准龄期养护下的同一配合比不同掺料的相变混凝土立方体试件进行了抗压与劈裂抗拉强度试验与分析.试验结果表明,除3 d龄期外,单掺硅粉相变混凝土在不同龄期下的抗压能力均高于其他掺料相变混凝土;单掺粉煤灰相变混凝土在不同龄期下的抗拉能力均低于其他掺料相变混凝土;双掺粉煤灰与硅粉的相变混凝土直到龄期达到90 d的时候,才会到达相变储能组的强度.
In order to prepare phase-change concrete with certain strength, the compressive and splitting tensile strength tests are carried out on phase change concrete cube specimens with different mixing ratios under different standard ages. The test results show that, except for the 3 d age, the compressive capacity of single silicon powder phase change concrete under different ages is higher than that of other mixed phase change concrete;the single flyash phase change concrete under different ages;The tensile strength is lower than that of other mixed phase change concrete;The phase change concrete mixed with flyash and silicon powder will reach the strength of the phase change energy storage group until the age reaches 90 d.
