Recycled　concrete　brick　is　made　of　discarded　concrete.　As　a　basic　study　for　the　aseismic　behavior　of　recycled　concrete　brick,　the　compression　properties　of　18　recycled　concrete　brick　masonry　specimens　in　different　levels　of　mortar　strength　were　tested.　The　load-bearing　capacity,　deformation　and　the　failure　process　of　each　specimen　were　tested　and　analyzed.　Then,　the　compression　strength,　elastic　modulus　and　Poisson＇s　ratio　of　recycled　concrete　brick　were　calculated.　The　research　shows　that,　compared　with　common　bricks,　the　recycled　concrete　brick　has　a　lower　load-bearing　capacity　and　a　faster　decline　in　pressive　strength,and　the　elastic　modulus　and　PoissonS　ratio　are　nearly　the　same.　With　the　increased　strength　of　masonry　mortar,　the　pressive　strength　and　deformability　increase　and　the　elastic　modulus　augments.　The　recycled　concrete　brick　can　be　used　in　the　seismic　design　of　multi-layer　masonry　buildings.
