By simulating the hydrothermal solidification technique of underground rock formation mechanism,the sludge soil is dehydrated and mixed evenly with lime,recycled aggregates,etc.,and then pressed into bricks.The bricks are then cured under high temperature and high pressure in an autoclave to undergo hydrothermal solidification reaction inside,forming green and envi-ronmentally friendly hydrothermal solidified slag soil bricks.To study the basic mechanical properties of hydrothermal solidified slag soil brick masonry,hydrothermal solidified slag soil brick masonry was designed and fabricated,and axial compressive tests were conducted to investigate the effects of brick type,mortar type,and strength on the failure process,load deformation characteristics,compressive strength,and elastic modulus of the masonry.The results showed that the compressive strength design value and aver-age elastic modulus of hydrothermal solidified slag soil brick were 38％and 44％higher than the requirements of GB 50003-2011,respectively.This product can be used to replace traditional wall materials in practical engineering applications.
