Abstract: Salt weathering is one of the most common deterioration mechanisms in porous materials and may lead to severe damage. Much work has been done to explain the mechanism of crystal growth and its relationship with degradation of materials such as mortar and concrete. Fired bricks are widely used in Chinese ancient buildings, constituting walls and floorboards. A preliminary experimental study on fired bricks submitted to sulfate attack was conducted. Relative dynamic modulus of elasticity was utilized to characterize the deterioration progress of fired brick under salt crystallization cycles through wet-dry method. Compressive strength changes and weight loss also disclosed explicit regularity.
