RESEARCH ON COMPRESSIVE BEHAVIORS OF N-TYPE BLOCK MASONRY

摘要

N-type concrete masonry is a new type of small-size concrete block masonry by improving the 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 show that the average compressive strength of ungrouted N-type masonry increased 30%-52% and of the grouted N-type masonry increased 8%-45% compared to the common concrete masonry. The main reason for the strength rising is the full-alignment of web-shells in N-type concrete masonry prisms.
