This two day symposium and workshop will explore built concrete works specifically through consideration of their surface. Valued for its strength and durability, concrete has challenged and expanded the meaning and role of the architectural surface during the material’s long and evolving deployment. The symposium will explore historical approaches to the finishing and surface treatment of concrete as well as its performance, deterioration, and conservation. Of particular interest will be past and contemporary attitudes toward aging and extended service life and methods for repair.

Day 2: Workshop
Saturday, February 10, 2018
Day 2 of the event will be held at the IMI/BAC Local 1 Training Center and will focus on the current materials and methods for addressing treatment repairs to concrete surfaces. The event will showcase manufacturer representatives demonstrating a variety of products that are relevant to the program and topics at hand. Vendors demonstrating include:
Participants will also take part in a non-proprietary exercise for matching historic concrete with raw materials. This session will provide an overview of proper repair procedures including general surface preparation, general mix design characteristics, and the methodology and steps for matching repairs to historic concrete. The overview session will be followed by 4 interactive stations as follows:
Station 1: Microscopes to look at polished concrete samples and thin sections
Station 2: Measuring color of existing concrete, various cementitious materials, and blends and color-blind test.
Station 3: Mixing sample batches with cementitious, sand, and coarse/pea gravel.
Station 4: Finishing samples with a variety of sponges or retarded forms.
These interactive demonstrations will allow the participants to better understand these materials, properties, and proper installation techniques. Program participants will also have the ability to interact with current masonry apprentices and tour the training facility. Transportation and lunch will be provided.
