This work uses a new cementitious agent composed of porcelain polishing waste and hydrated lime in the mitigation of static liquefaction in a loose dune sand. The undrained behavior of the soil was investigated in 16 triaxial tests under four confining stresses (50, 100, 200 and 400 kPa), on loose samples (relative density of 25%) compacted with two levels of waste (10% and 30%) and lime contents (3% and 7%) cured at 28 days. Stressstrain behavior, ultimate strength and critical state parameters were evaluated. The results showed a brittle response of the stabilized sands, dilatant tendency and low liquefaction potential, however, the behavior changes with the increase in the confining stress. A friction angle of up to 42.6 degrees and a cohesion intercept of up to 108.1 kPa were found for the stabilized sand. When compared to the pure sand, stabilization caused an increase in strength, of up to 17 times, and in brittleness with a change from contractive to dilatant behavior. For tests up to 200 kPa, the liquefaction potential reduced to values below zero. Therefore, the cementation of the grains by using porcelain polishing waste and hydrated lime was efficient in mitigating the static liquefaction potential of the dune sand.
