www.concreteproducts.com August 2019 • 59 TECHNICAL TALK PERFORMANCE MORTAR The diagrids' energy and material efficiency owes to light surface characteristics and strength development from optimized mortar mix de- sign. BASF Construction Chemicals Technical Center scientists cast the mortar elements—flowers (shown here at pouring), squiggly mazes, sand castles and peaks—earlier this spring on a tight timetable dictated by the May 2019–January 2020 Cooper Hewitt Monarch Sanctuary exhibit schedule. Casting necessitated material with spread properties similar to self-consolidating mixes, and included alignment of bracket hardware with which the diagrid elements could be readily mounted on the exhibit's wooden frames. Live monarchs were brought in to test the initial exhibit layout.
