The two-day workshop will primarily cover preservation philosophy and approach for modern concrete and cement-based terrazzo flooring systems. The workshop format will include presentations with integrated case studies, studio visit with demonstrations by craftsman, mini-laboratory, along with visit to a site of an ongoing concrete conservation project. Specific topics will include assessment and nondestructive testing, laboratory studies, concrete cleaning, repairs (including matching modern historic concrete), corrosion mitigation, and protection.
The mini-laboratory session will led by a petrographer and include hands-on microscopic evaluation by attendees of concrete and terrazzo samples with microscopes and other laboratory equipment. In addition, various types of non-destructive testing equipment will be demonstrated to and used by attendees.
The visit to a working studio will include demonstrations by conservators and contractors with extensive experience with historic concrete and terrazzo flooring. The demonstrations will be hands-on and allow for attendees to closely interact with the craftsman to allow for questions on techniques.
The final portion of the workshop will be a visit to working preservation project to see how the philosophy and approach are put into practice. The contactor and craftsmanship will help guide the site visit which will include concrete cleaning, removal of paint, development of mix designs, matching of concrete, and other repair techniques.
