Title:State of Practice for Concrete Cylinder Match Curing and Effect of Test Cylinder Size
Author(s):Popovics, John S.; Ham, Suyun; Garrett, Stephen
Subject(s):Prestressed concrete
Match-curing cylinders
temperature-controlled chambers
Abstract:The prestressed concrete element industry is interested in exploring the application of different types of match-curing technologies and in using 4 x 8-in. (100 x 200-mm) cylinders to measure concrete compressive strength instead of the standard 6 x 12-in. (150 x 300-mm) cylinders. Application of this new technology creates potential for cost savings to the producer and the Illinois Department of Transportation (IDOT) as improved knowledge of concrete strength development allows more efficient and accurate stress release and form removal times, normally within 24 hours after casting. The technology associated with match-curing cylinders is somewhat new, and little information is available on the use of temperature-controlled chambers for match curing. This study explores the effects of match-curing performance specifically taking into consideration the insulated jacket mold and air chamber technologies, as well as the effect of cylinder size. This research effort consists of five objectives: (1) review of the literature, current industry practice, and available technology; (2) purchase, assembly, and verification of the effectiveness of match-curing technology; (3) study of the effect of system temperature control on match-cured (water bath) strength results; (4) study of the utility of using match-curing technologies (insulated jacket mold and air chamber) to estimate 1-day, in-place compressive strength; and (5) study of the effect of cylinder size on match-cure strength results.
