Abstract
This paper presents a study of skin friction change of cement pastes used for micropiles as a geotechnical foundation when grout surface is affected by sulfate attack. In this research skin friction coefficient between cement paste - cement paste was measured, studying change in friction depending on the initial roughness of samples. Tests were performed after 3 and 6â¯months of immersion in a 15% Na2SO4 solution. Results show that sulfate attack increases skin friction coefficient for both surface finishes, concluding that this attack does not have a negative effect on friction in the experimental conditions of this work.
