|Title:||REACT: Reducing Early-Age Cracking Today|
|Published:||June 01, 2008|
|Abstract:||Concrete is generally viewed as a durable and long-lasting construction material. However, the long-term performance of a concrete structure can be greatly compromised by early-age cracking. One recent informal estimate from the industry places this as a $500 M problem in the U.S. alone, with some ready-mix companies experiencing early-age issues on as many as 70 % of their jobs. As is often the case, as a problem intensifies, mitigation strategies are developed and promoted from the research laboratory to the field. This paper will briefly review the most common non-structural causes of early-age cracking and present an introduction to various mitigation strategies. These strategies are being further investigated as part of a newly formed university/industry/government collaboration under the acronym of REACT: Reducing Early-Age Cracking Today.|
