To accomplish these goals, this research is designed to measure the effect of the differences in the environment provided by different grouts and to compare the level of corrosion caused by filling the voids with an anti-bleed grout to that resulting if the strands are not re-grouted but are subjected to water or water containing chloride. 收起
