ROBERT G. DRYSDALE AND PING GUO
ABSTRACT
A dry-stacking, interlocking type of block, known by the trade name of sparlock, was tested to determine loadbearing properties for axial compression and out-of-plane bending about both the horizontal and vertical axes. Prisms and small walls were built as plain masonry, surface bonded masonry and grouted and reinforced masonry. Loadbearing capacities comparable to traditional masonry were obtained for the latter two forms of construction and even the interlocking in the plain form of construction (i.e., no mortar, surface bonding, or grout) provided significant stability and strength.
