中文摘要：
当再生混凝土中再生骨料的取代率为0、40%、60%、80%、100%，橡胶颗粒取代率为10%、20%、30%时，分析再生混凝土多孔砖、掺入橡胶颗粒后再生混凝土多孔砖的抗压强度、抗折强度及导热系数的变化规律。试验结果表明：随再生骨料掺量的增加，砌块抗压强度、抗折强度先增加，达到40%时最大，后呈下降趋势；随橡胶颗粒掺量的增大，砌块抗压强度、抗折强度随之下降，保温性能提高。
英文摘要：
When replace rate of recycled aggregates were 0,40%,60%,80%,100%,replace rate of the rubber are 10%,20%,30%, analyse the change rules of the compressive strength,flexural strength and thermal conductivity of the recycled concrete porous brick.The results showed that the compressive strength and flexural strength of brick was increased at first and then reduced with the rate of recycled increase,when the rate was 40%the both strengths would be the maximun;With the increase of rubber,the compressive strength,flexural strength reduce and the thermal conductivity of the recycled concrete porous brick was increase.
