LONG-TERM STUDY ON PHYSICAL PROPERTIES OF HIGH-STRENGTH MASS CONCRETE

－Results of 36-year monitoring test using simulated mass concrete members－

Abstract

To assess the durability of concrete structures located at waterfront sites, a long-term test to monitor the physical properties of core specimens sampled from simulated high-strength mass concrete members was carried out. The study focused on changes over time of compressive strength and elastic modulus, the tendency of depth direction from the concrete surface, as well as the tendency of dry mass per unit volume. The test results confirmed the integrity of high-strength mass concrete up to 36 years age.
