摘　　要：以相变温度为24℃的混合石蜡作为相变材料,采用多孔粉煤灰陶粒进行吸附,以吸附石蜡的陶粒作粗骨料,按照混凝土制备工艺制备相变混凝土,并与空白试件进行对比,然后测试二者在有热源情况下的升温能力及撤掉热源后的降温能力。试验结果表明,相变混凝土试块升温/降温过程都较空白试件缓慢,石蜡相变材料起到一定的调温作用。Mixed paraffin,which the phase-transition temperature is 24℃ were used as phase-change materials （PCM）,using the porous sintered fly ash to adsorption,the ceramsite were used as coarse aggregate after adsorption of paraffin,according to preparation technology of concrete to prepare phase change concrete,and set the blank sample,then under the condition of a heat source to test heating ability and the ability to cool down after the heat removed. Research shows that：phase change concrete blocks are slower than blank specimen during heating/cooling process,paraffin phase change materials play a certain effect of regulating temperature.
