The brick to mortar bond is a mechanical bond produced by the intrusion of a cementitious paste into the pores of the brick. The issue of creating an efficient bond between bricks using mortar has been studied in great detail. Several factors can affect the bond strength of brick masonry units, such factors include: Initial rate of absorption (IRA) of water for bricks, brick porosity, brick texture, type of mortar, type of sand, mix proportions, mortar water content, mortar workability, mortar

... iscosity, time between the application of mortar and placement of the brick, and placement method. This paper presents a research study conducted to determine the effect of robotic brick placement on the bond strength between bricks and mortar using the Bond Wrench Test as described in ASTM C1072.
