摘要： 通过活性试验对陶泥进行活性测试及评价，并将陶泥作为混凝土辅助胶凝材料，探讨了陶泥对混凝土抗压强度的影响.试验结果表明，陶泥具有反应活性，作为混凝土辅助胶凝材料能与混凝土中水泥水化产物Ca(OH)2发生二次水化反应；陶泥混凝土抗压强度与基准混凝土抗压强度随龄期发展规律相似；随着陶泥取代水泥量(质量分数)的增加，混凝土各龄期抗压强度呈下降趋势；陶泥取代水泥量不超过30%，混凝土强度等级可达到设计强度等级C30或C40；取代量相同时，陶泥混凝土与粉煤灰混凝土各龄期抗压强度比较接近.

Abstract: The activity of ceramic polishing powder was tested and evaluated by activity test. Taking ceramic polishing powder as supplementary cementing materials for concrete， the effects of the ceramic polishing powder on concrete compressive strength was studied. It is showed that the ceramic polishing powder possesses reaction activity， it can interact with Ca(OH)2， i. e.， secondary hydration reaction. The development trend of compressive strength of ceramic polishing powder concrete with age is similar to that of plain concrete. The concrete compressive strength at different ages declines with increasing mass fraction of cement replaced with ceramic polishing powder. If the mass fraction of replacement is not more than 30%， the strength grade of concrete can be at the level of C30 or C40. Finally， with the same mass fraction of replacement， the compressive strength of ceramic polishing powder concrete approximates to fly ash concrete at different ages.
