Cement grouts for post-tensioning tendons ensure durability of the system. Voids formed from bleeding of grout may result in loss of a protective environment that may lead to corrosion of prestressing steel. This test method is a tool to evaluate the bleed stability of a grout under static pressure and can be used to prequalify grout materials or for quality control.
