Abstract: This study aims to present the results of a test programme taken onsmall size concrete-backed stone prisms built with medium-density limestone. The effect of the size of the prisms on the ultimate compressive strength was studied. The behaviour of prisms until failure was also studied. Large numbers of small size prisms with different thicknesses, widths and same mortar joint thickness and mix proportions for either mortar or concrete were tested in compression. Two groups of stone were adopted in constructing the prisms, the first group was built using regular stone thickness and the other group with irregular thickness. The test results express a significant increase in compressive strength when small prisms were built from stone units with regular thicknesses.
