Early age cracking, including unplanned random cracking, is of major concern for Engineers, Designers, Specifiers, Concrete Suppliers, Concrete Finishers, Concrete Cutters, Contractors and Property Owners. This Seminar addresses some of the issues involved and will discuss suggestions as to how such cracking can be effectively controlled.

My headstock thermal differential went over 25 oC and it didn’t crack, what’s going on?
Greg’s presentation will cover thermal deformation, autogenous and drying shrinkage, restraint, and the impact of mix/materials on why predictions of thermal cracking are problematic, also can bring in the new CIRIA 766 (replacing C660) and some of the CIA durability work with regard to determining crack widths.
