Join DRP, a Twining Company, for a free webinar on recognizing and understanding the role of salts in scaling and freeze – thaw damage
Scaling of pavements and concrete flatwork is a widespread phenomenon in areas where we count snow and ice as two of winter’s pleasures.
Over the past 10-15 years, many state and municipal agencies, along with private property owners, switched to more aggressive maintenance practices, such as using harsher deicers containing calcium chloride (CaCl2) and magnesium chloride (MgCl2). Consequently, premature scaling (occurring within a year or two of construction) is now a common source of disputes between materials suppliers, contractors, designers, and owners.
DRP’s webinar will:
- Review how scaling mechanisms bring the intersection of material properties and construction and maintenance practices to the fore
- Highlight case studies to illustrate how various petrographic and laboratory techniques help us recognize and understand the factors that underlie scaling and distinguish it from classical freeze-thaw damage. In particular, we will present a recent case study highlighting the role of calcium oxychloride in freeze-thaw damage.
