Nowadays, the use of flat blocks covered up by thin mortar joints (1 to 3 mm thick) represents one of the more promising constructive systems for load bearing masonry walls. The easier execution in comparison with the traditional system allows significant reduction of construction times and quantities of mortar, with very favorable consequences on the global costs. In the paper, the results of a comparative experimental study carried out on the new system and on ordinary masonry are presented. Mechanical tests have been performed on masonry specimens, to clarify the behavior both under compression and shear loads. The main results are discussed, as well as the effectiveness of special mortars and different modalities for the execution of thin joints.

Abstract
Nowadays, the use of flat blocks covered up by thin mortar joints (1 to 3 mm thick) represents one of the more promising constructive systems for load bearing masonry walls. The easier execution in comparison with the traditional system allows significant reduction of construction times and quantities of mortar, with very favorable consequences on the global costs. In the paper, the results of a comparative experimental study carried out on the new system and on ordinary masonry are presented. Mechanical tests have been performed on masonry specimens, to clarify the behavior both under compression and shear loads. The main results are discussed, as well as the effectiveness of special mortars and different modalities for the execution of thin joints.Pubblicazioni consigliate
