SIGNIFICANCE AND USE 5.1 This test method is useful for determining the expansion and bleeding characteristics of freshly mixed fluid hydraulic cement grout commonly used in PA concrete and cementitious post-tensioning tendon grouts.
Abstract
Overview
provides a reliable laboratory method for assessing the expansion and bleeding characteristics of freshly mixed fluid hydraulic cement grout. This standard is essential for quality control and mix design verification in preplaced-aggregate (PA) concrete and cementitious post-tensioning tendon grout applications. By measuring both the expansion and the accumulation of bleed water, the method helps ensure mixture performance, stability, and long-term durability in the field.
