ABSTRACT
A light-weight, oversized concrete block manufactured using saw dust as aggregate and marketed under the trade name of ENVIROBLOCK™ , was tested to find material and structural properties under several loading conditions. These included out-of-plane bending, in-plane shear, eccentric axial load and pure compression. Both ungrouted and fully grouted specimens were made with the fully grouted samples being either reinforced or unreinforced. The ability to use standard design practices represented in masonry design codes was confirmed with the exception of tensile bond for ungrouted construction.
