Abstract [en]

According to good practice within the Swedish masonry industry brick beams needs to be underpinned during the 28 first days. Masonry craftsmen and construction engineers believe that the supports can be disassembled before this time has elapsed. This will facilitate subsequent entrepreneurs to begin their work earlier. Previous studies on this subject haven’t been done. Within this project tensile tests have been made in order to find out how the adhesion between brick and mortar develops over time, and how the temperature affects it. The aim has been to test if the adhesion is strong enough to remove the underpinning earlier than 28 days. Interviews with bricklayers and project managers have been done to get their point of view on the problem. The result of interviews showed that bricklayers removed the underpinning earlier than 14 days, the results of the traction tests did show that the underpinns can’t be removed after an exact number of days. What determines if the stamp can be picked up earlier is the size of the opening and the temperature it cures in.
