Abstract:
Describes an experiment to measure the loss in strength and permeability of concrete resulting from interruption of moist curing, and the subsequent regain in these properties due to recurring. Cement mortar specimens were subjected to curing interruptions after moist curing periods of 0, 3, 7, 14, and 28 days. After interrupting the curing, the specimens were divided into two groups: one group was recurred, while the curing of the other group was discontinued. At the end of the recurring period, both groups of specimens were tested for compressive strength and water absorption. The recurred specimens showed significant gain in strength and reduction in water absorption.
