• Abstract:
  The prestressed concrete element industry is interested in exploring the application of different types of matchcuring ; 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.
