An experimental study is carried out on running bond clay prisms subjected to axial compression for the influence of grout with a view to find out efficient grout proportions in order to enhance the capacity of masonry. With this purpose different parameters that affect the compressive strength (mortar type, grout strength and percentage of grouted cells) were used to the construction of the prisms. The specimens of three courses were tested at 0%, 33%, 50% and 100% of grouted cells for two different types of mortar, and three grouts. The results show that the compressive strengths of mortar and grout are not fully reflected in the strength of grouted prisms, but it is possible to achieve significant increases of strength mainly in the100% grouted cell prisms. This fact could be very attractive to unreiforced masonry design when more resistant blocks are required only in not many walls. In addition, elastic analysis utilizing finite element models were made to better explain the behavior of the grouted, partially grouted and ungrouted clay prisms.
