Papermaking white clay sintered porous brick shale is as a paper mill alkali recovery process to produce large amounts of white mud and research and development of a new type of wall materials, because of the brick in material performance differences and common brick, used as a filler wall when its compressive strength does not have a corresponding formula calculation. In order to verify the formula for calculating the compressive strength of the masonry specification , this paper take strength grade for MU5, MU7.5 mortar, respectively the papermaking white clay sintering production 6 groups of masonry shale porous brick masonry masonry compression test, by studying the process of damage, it is concluded that compressive strength of masonry, the brick masonry is verified and can be used in "masonry structure design code" calculation formula to calculate the compressive strength. The papermaking white clay sintered shale were studied the deformation properties of porous brick masonry, through the analysis, draw the stress-strain curve, it is concluded that the elastic modulus .
