【摘要】：为了制备具有保温储热能力,同时具有一定强度的新型混凝土材料,对不同活性炭储能骨料掺量的相变混凝土进行了抗压强度、劈裂抗拉强度和导热系数试验,并对试验结果进行了分析。试验结果表明,掺入活性炭储能骨料降低了相变混凝土的抗压、劈裂抗拉强度,活性炭储能骨料掺量在15%以内,相变混凝土的强度损失率不超过10%。相变材料为液态时相变混凝土的导热系数略大于相变材料为固态时的导热系数,增加幅度低于5%。随着活性炭储能骨料掺量的增加,相变混凝土的导热系数增大明显,满足保温要求,活性炭储能骨料的掺量应在15%以内。
[Abstract]:The compressive strength, splitting tensile strength and thermal conductivity of phase change concrete with different amount of activated carbon aggregate were tested in order to prepare a new type of concrete material with heat preservation and heat preservation capacity at the same time. The test results are analyzed. The experimental results show that the addition of activated carbon energy storage aggregate can reduce the compressive strength and splitting tensile strength of phase change concrete. The content of activated carbon energy storage aggregate is less than 15% and the strength loss rate of phase change concrete is less than 10%. The thermal conductivity of the phase change concrete when the phase change material is liquid is slightly larger than that of the phase change material when the phase change material is solid, and the increase is less than 5%. With the increase of the amount of activated carbon aggregate, the thermal conductivity of phase change concrete increases obviously, which meets the requirement of heat preservation. The content of activated carbon energy storage aggregate should be less than 15%.
