Masonry with soil cement bricks is an interesting alternative due to its reduced environmental impact. However, the use of modular bricks fitted together and without laying joints generates low resistance capacity in these load-bearing wall systems. Therefore, it is necessary to better understand the effect of thin joints in this masonry. The objective of this study was to investigate the influence of the type of material and application of the laying joint on the compressive strength of prisms with soil cement bricks. For this, the compressive strength of prisms made with three joints of different materials (polymeric mortar, adhesive mortar, and acrylic glue - Tijofix) and two types of application (continuous or discontinuous) was evaluated. It was found that non-uniform joints reduce the compressive strength by more than 50% and that the presence of adhesive and/or polymeric mortar joints tends to maximize the resistance capacity of masonry with soil cement bricks.
