摘　　要：采用半干压成型法,研究了粉煤灰-页岩二元体系在不同烧结制度下的物理力学性能变化规律,结果表明:粉煤灰与页岩的配合比和烧结温度对烧结制品的性能影响显著,制品烧结收缩与其密度、吸水率及开气孔率成负相关性。在本试验条件下,粉煤灰掺量为50%、烧结温度为1000℃时制品的综合性能最佳,但烧结温度过高时易出现反致密化现象,1100℃时坯体已膨胀变形。Extruding billet by semi-pressure molding method, study is made on variation of physical mechanics property of fly ash and shale binary system under different sintering system. The results show that： the mixing proportion of fly ash and shale and sintering temperature have remarkable effect on the performance of sintered products,and the product sintering shrinkage has an inverse correlation with its density,water absorption and open porosity. Under the test condition of fly ash content 50% sintered at 1000 ℃the product has the best all round performance,but counter-densification phenomenon occurs easily by over high sintering temperature,the billets are severely deformed at 1100 ℃.
