Description

Concrete cracks. It's a fact of life. The uncertainty and challenges lay in determining the reason why a concrete structure or element has cracked.

In this course, WJE petrographers Daniela Mauro and Karla Salahshour will discuss common causes of concrete crack formation and will share case studies from their own experience that highlight a range of conditions, including cracks that appeared to be structurally significant when observed in the field but were later determined through laboratory studies to be less severe. The presentation will examine crack aging, construction techniques to reduce some types of cracking, and uncommon deterioration mechanisms -- illustrated with field images and photomicrographs.

Course will award 1.5 hours of continuing education
This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.

Daniela Mauro specializes in the evaluation, investigation, and characterization of construction materials. Her background includes more than fifteen years performing petrographic examinations and laboratory testing focused on concrete, mortar, aggregate, dimension stone, stucco, and other building materials. Ms. Mauro has been involved with hundreds of projects involving the investigation of concrete problems, including low strength issues, surface defects, cracking, sulfate attack, delayed ettringite formation, and alkali aggregate reactivity. In addition, she has extensive experience examining modern and historical materials for rehabilitation projects, and uses her experience in scanning electron microscopy, optical microscopy, laboratory testing, and field investigations to provide a comprehensive approach to her work.

Karla Salahshour, P.E., specializes in the evaluation and characterization of historic and modern building materials. Her work in WJE’s Cleveland materials laboratory focuses on the petrographic examination of concrete, mortar, grout, brick, stucco and plaster, natural and manufactured stone, and other construction materials. Ms. Salahshour’s laboratory work has included investigating the causes of distress in construction materials, characterization of cementitious materials, and the evaluation of durability concerns in hardened concrete. Ms. Salahshour also conducts field evaluations, such as evaluating distress in concrete slabs and pavements and evaluating the performance of coating systems. Her field experience also includes the investigation of stone cladding panels, mass masonry structures, terra cotta facades, EIFS and stucco systems, and terrazzo.

NCSEA Webinars and Digital Events Cancellation and Refund Policies

Webinar Cancellation
