Concrete Distress &
Deterioration - Symptoms and Causes
Tomas Orihuela, P.E.
Overview
A basic understanding of the underlying causes of concrete deficiencies is
essential to performing meaningful evaluations which lead to the proper
selection of the method or technique used to successfully repair concrete.
Symptoms or observations of a deficiency must be differentiated from the actual
cause of the deficiency, and it is imperative that causes and not symptoms be
addressed in repairs. Deterioration of concrete is an extremely complex subject
since, in most cases, the damage detected will be the result of more than one
mechanism.
In this course, the student will review Chapter 3, Causes of Distress and
Deterioration of Concrete from Engineer Manual (EM) 1110-2-2002,
“Engineering and Design – Evaluation and Repair of Concrete Structures”
published by the U.S. Army Corp of Engineers (issued 30 June 1995). This course
is most relevant to engineers wishing to attain knowledge on the most common
causes of problems in concrete. The course also provides a brief description of
the basic mechanism of each common problem, a description of the typical
symptoms that would be observed during a visual inspection, and suggests
preventative methods or techniques to prevent further damage.
The student must take a
multiple-choice quiz consisting of ten (10) questions at the end of this course
to earn PDH credits.
