How to reduce and eliminate joints and curling?
GreenCanvas Expansive Component
GreenCanvas expansive component is a cementitious inorganic powder, when added to a standard concrete mix, will produce a shrinkage compensating concrete (SCC); Type G (ACI-223R-10) .
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” and compliance and quality assurance can be measured by standard ASTM tests and procedures.
