Stabilized mud blocks (SMBs) are manufactured by compacting a wetted mixture of soil, sand, and stabilizer in a machine into a high-density block. Such blocks are used for the construction of load-bearing masonry. Cement soil mortar is commonly used for SMB masonry. This paper presents the results of an experimental investigation in characterizing the properties of SMB masonry using cement-soil mortars. The compressive strength, stress-strain relationships, and elastic properties of SMB masonry using three types of SMBs and cement-soil mortars are discussed. The influence of a cement-soil mortar's composition and strength on masonry characteristics is examined. The results of masonry using cement-soil mortars are compared with those using conventional mortars (cement mortar and cement-lime mortar). Some of the major findings are: (1) SMB masonry strength is sensitive to block strength and increases with increase in block strength; (2) the strength of SMB masonry using cement-soil mortars is more sensitive to the cement content of the mortar than to the clay fraction of the mortar mix; (3) the masonry modulus increases as the block strength increases; and (4) SMB masonry with cement-soil mortars shows higher modulus than the masonry using cement mortar and cement-lime mortar.
