“…33 It was stated that a thin layer of cement was poured on the brick loading surface before the compression test. 34,35 In the first way, rough surfaces of the bricks were kept as they are but covered with a cement and gypsum mixture to have a smooth surface during the axial load application. In the second way, surfaces of the bricks were smoothened, and then cement-gypsum mixture capping was applied.…”

SummaryAs a result of the combination of the complex behavior of masonry buildings with insufficient material quality and lack in engineering calculations, a large number of damages has been observed in the earthquakes that occurred in recent years. Therefore, a realistic understanding of the behavior of masonry walls and buildings is necessary to construct seismic‐resistant structures. Since masonry walls have many variables, performing experiments in which each variable is present at the same time will make it difficult to understand the behavior. For these reasons, considering the out‐of‐plane failures that are frequently mentioned in recent earthquakes, in this study, variables in dry‐stack brick masonry buildings such as the aspect ratio of the wall (2, 1.33, and 1), the presence of the transverse walls (2, 1, and 0), and the openings in the walls (door and/or window) were taken into account separately. Eighteen different wall configurations were designed, and a total of 48 dry‐stack walls having U‐shape, L‐shape, and I‐shape in plan were tested by a specially constructed tilting table setup to determine their out‐of‐plane behavior. From the test results, it was found that lateral load capacity of the U‐shaped walls without openings increased as the aspect ratio (L/H) decreased. No change in capacity was observed in L‐ and I‐shaped walls when the aspect ratio was reduced from 2 to 1. Door and/or window openings were found to affect only the L‐shaped walls. In addition, it was determined that failure patterns were affected from the aspect ratio and the presence of the openings.

“…Prisms can present only horizontal joints or horizontal and vertical joints. Results from studies performed by some researchers suggest that the non-fulfillment of the vertical joints has little effect on the resistance to compression and in the deformation module of the masonry, being more relevant to the shear resistance [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. As this is a study on the performance of the PBB facing simple compression, this article presents only cases where vertical mortar joints were not used.…”

In the search for better constructive efficiency and a reduction of the waste of construction materials, several researches have been performed in the last years around the world. Red ceramic blocks are artifacts widely used in civil construction around the world, and they result in a great consumption of raw materials and energy. The great innovation of this research was the development of ceramic blocks through an innovative method of pressing and dosing materials, replacing the traditional stage of extrusion in the manufacture of ceramics. In such a sense, a new manufacturing technology for ceramic blocks was proposed through the pressing process, adapting the soil-cement brick press machine, thus attaining more even pieces with greater compliance to the dimensions and preset geometry. In this work, the physical and mechanical features of the pressed and burned blocks (PBB) are produced in a partnership with Arte Cerâmica Sardinha, a traditional ceramic industry in the region of Campos dos Goytacazes, RJ, Brazil. It was sought to set the quality parameters for the blocks, to set their mechanical compressive strength, deformation modules and the Poisson coefficient. The blocks were tested in use by means of three layers of prism and small wall samples, and it was checked the fragile-type failure of the PBB. Results indicate that the blocks can be employed in small-sized construction works, as the characteristic compressive strength to block measured was 3.62 N/mm2 for average water absorption of 20.84%.
