Abstract:Taking the actual project as a typical case,we analyze the causes of cracking and damage of sintered porous brick walls by testing the compressive strength,weathering resistance,lime bursting and frosting performance of sintered porous bricks after many years of construction,and by combining the material damage of the on-site investigation,the rainfall of the location of the building,and the water situation.When the sintered porous brick walls are exposed to a high water content and low temperature environment for a long time,cracks in the plastering mortar layer cause the moisture inside the sintered porous brick to reach sat-uration.When the temperature drops to freezing point,the volume expansion caused by the freezing of the moisture inside the structure leads to cracking of the brick body and an increase in the cracks in the plastering mortar layer,allowing more moisture to enter the brick body and exacerbating the degree of wall cracking and damage.At the same time,the cracking and frosting of lime within the brickwork also exacerbated the damage process of the brick body.
