Title: Measurement of Early Age Shrinkage of Virginia Concrete Mixtures
Contact: Soundar Balakumaran
Associate Director for Structures
Project No.: 82140
Target Date: 02/26/2008
Abstract: This study will examine the early age volume change of a variety of concrete mixtures used by the Virginia Department of Transportation (VDOT).  This will be done using traditional ASTM C 157 specimens.  The rigid form method, which incorporates the use of a non-contact laser, will be used to measure the earlya age volume change of specimens immediately after the specimens are cast.  It is anticipated that this investigation will be able to determine if the rigid form method can be implemented by VDOT in measuring early age volume changes.  The investigation should also aid in determining if the mixtures tested have a significant amount of early age shrinkage which could lead to a higher probablility of cracking.
