EC9 Nine Fundamentals for Expansive Components for Shrinkage Compensating Concrete

Using an Expansive Component, we can produce what many thought impossible; reducing or eliminating concrete curl, simplifying joint layout through reduction/elimination of control joints, and eliminating dry shrinkage cracking. This naturally found, cementitious, the inorganic powder will produce a shrinkage compensating concrete when added to standard concrete mix designs. Profiled architectural concrete floors with an expansive component promote even aggregate reveal desired by owners and design professionals and eliminate joint maintenance. In addition, it will increase the life cycle, abrasion resistance, durability, tensile strength, and water tightness of the finished concrete placement. Shrinkage compensating concrete increases the resistance to chloride intrusion and increases abrasion resistance. SCC has a concrete life cycle of up to 2 1/2 times conventional concrete for several reasons. Its mechanical bond with reinforcement, the lack of cracks, and the dense microstructure can eliminate the need for re-bar coating in the harshest of environments.
