Learn how different types of mortar significantly affect the performance of masonry buildings with Mario Machnicki, masonry consultant and president of U.S. Heritage Group, Inc., on Thursday, Aug. 21, at 12:15 p.m. at the Chicago Cultural Center, 78 E. Washington St., Fifth Floor Meeting Room.
The mortar system is the most crucial element in the successful performance of all masonry. The basic concepts of mortar performance are important for all preservationists to understand. Cement and lime-based mortars have radically different characteristics, which impact the longevity of historic masonry. Case studies will illustrate the consequences of using both types of mortars.
