摘　　要：对6个未灌孔及12个灌孔的N式砌块砌体进行了受压性能试验研究，了解了N式砌块的破坏形态及破坏机理．试验结果表明，未灌孔的N式砌块砌体的抗压强度平均值较普通混凝土小砌块抗压强度平均值提高了30％～52％，灌孔的N式砌块砌体的抗压强度平均值较普通混凝土小砌块抗压强度平均值提高了8％～45％．分析表明，其强度提高的主要原因是N式砌块砌体实现了孔、肋对齐．N-type concrete masonry is a new type of small-size concrete block masonry with improved block shape to realize fully aligned web-shells. Based on 6 ungrouted specimens and 12 grouted specimens, the compressive behaviors of N-type masonry were investigated. Test results showed that the average compressive strength of ungrouted N-type masonry increased by 30% --52 % and that of the grouted N-type masonry increased by 8 %-45 % compared with the common concrete masonry. The main reason for the strength increase was the full-allgnment of web-shells in N-type concrete masonry prisms.
