The aim of this work is to determine, as close as possible, the mechanical properties of the masonry units and mortar produced and used in Croatia for regular masonry buildings. In order to investigate the mechanical properties, bricks have been separated into categories and an experimental test setup prescribed by the prENV 1996-1-1:2004, has been used. The experimental methods and results of the preformed tests are presented for four different brick elements: block, thermo-block, concrete block and aerated-autoclaved concrete blocks. The mortar used is a cement-lime mortar M5. Tests performed are typically used for determination of the groups of masonry units, compressive strength of a brick, shear strength of the wall segments, compressive strength of the wall segments and modulus of elasticity of the masonry. The performed tests create the main input data for any further analysis of the masonry buildings and they could be used as good reference for designers, brick industry and masonry builders in Croatia.
