GreenCanvas is a specialty concrete component classified by type, based on the chemical mechanism used to obtain expansion in the concrete matrix during the curing process. Structure design, concrete mix design, and placement guidance is provided by the American Concrete Institute (ACI) document ACI-223 “Guide for the Use of Shrinkage Compensating Concrete”. Compliance and quality assurance can be measured by standard ASTM test methods and procedures.
