摘　　要：系统的研究了砖瓦再生骨料混凝土的抗压强度、劈裂抗拉强度与砖瓦再生粗骨料的级配、强化处理方法、水灰比、砂率、单位体积用水量之间的关系,并得出合理配合比建议;同时探讨了不同取代率对砖瓦再生骨料混凝土抗压强度的影响规律。为废弃烧结砖瓦再生利用的进一步研究提供了重要依据。The systematic study on the relationship between compressive strength, splitting tensile strength of recycled sintered brick-tile con- crete and recycled brick-tile aggregate of with different graduation, strengthening treatment,water-cement ratio, sand rate,water quantity, and come to a reasonable mix proposed ~ At the same time, the change law of compressive strength with different replacement rate was acquired.Pro- vides an important basis for further study on recycling of waste sintered brick-tile aggregate.
