CHARACTERISTICS AND UTILIZATION OF COARSE AGGREGATES ASSOCIATED WITH D-CRACKING

Degree of saturation of the coarse aggregate and its response to freezing and thawing are important aspects of the problem of D-cracking. Studies have indicated that nondurable materials may reach critical saturation when the concrete is in contact only with capillary-held water. Sorption properties and freeze-thaw tests differentiate between durable and nondurable materials. Reducing maximum aggregate particle sizes, as indicated by laboratory freeze-thaw tests, is the most feasible method of improving durability.
