Welcome to our Chapter
The Connecticut Chapter of ICRI prides itself on bringing to our industry some eight technical sessions each year. Our meetings are held the second Wednesday of the month at the North Haven Holiday Inn in North Haven
Stop by Often - both here and at our meetings
The food is good, the networking invaluable and the technical sessions will make both you and your firm more productive and more informed. Our group consists of Owners, Engineers, Architects, Restoration Contractors and Material Specialists for all phases of both Concrete and Masonry Restoration
February Meeting
"Mechanical Anchor Strength in Historic Masonry Materials"
Wednesday - February 15th, 2012
Presentation will include: A testing program to evaluate two types of mechanical fasteners in both limestone and sandstone for pull-out and shear will be described in this course. The ultimate yield strength is correlated to both compressive strength and surface hardness of the sample stone. Stone quality was evaluated in situ using ultrasonic pulse velocity measurements. Pulse velocity is sensitive to stone density, stiffness, and flaws that may have a corresponding effect on anchor capacity. Development of a relationship between anchor capacity and stone characteristics, as measured using the ultrasonic pulse velocity approach, would permit classification of field-installed anchors requiring destructive pullout tests.
