New Publication By RJLG’s Concrete Expert Dr. Eric Giannini


Dr. Eric R. Giannini, RJ Lee Group’s expert in concrete durability, test method development, and nondestructive testing, has co-authored a new publication in Elsevier: Construction & Building Materials. The article is titled “Characterization of Concrete Affected by Delayed Ettringite Formation Using the Stiffness Damage Test”.

In this publication, Dr. Giannini and his colleagues apply the stiffness damage test (SDT) and new analysis procedures developed by Leandro Sanchez to concrete damaged by delayed ettringite formation (DEF). These tools have been heavily studied for their application to alkali-silica reaction (ASR)-damaged concrete, and it is their conclusion that they may be even better at characterizing damage from DEF.

Free access to the full article is available until February 3rd here.

About Eric R. Giannini, Ph.D., P.E.

Dr. Eric R. Giannini joined RJ Lee Group’s expert team in 2017 and brings his expertise in concrete durability, test method development, and nondestructive testing. Prior to joining RJ Lee Group, Dr. Giannini was an assistant professor in the Department of Civil, Construction, and Environmental Engineering at The University of Alabama from 2012 to 2017. At Alabama, he was awarded over $1.8M in external funding as PI or co-PI from a broad portfolio of federal, state, and industry sponsors including the National Science Foundation, Department of Energy, Federal Highway Administration, Alabama Department of Transportation, and Portland Cement Association (Southeast Region). Over the past 10 years, he has contributed to or led numerous research projects related to alkali-silica reaction (ASR) in concrete, addressing aggregate test methods, assessment and monitoring of field structures, and the development of laboratory mockups to simulate the development of ASR at multiple length and time scales. Dr. Giannini has partnered with experts in NDE and structural health monitoring (SHM) to investigate and validate the potential of new technologies to monitor the progress of ASR in concrete nuclear structures. As a PCA Educational Foundation Graduate Research Fellow, he developed an innovative ultra-rapid autoclave test method to assess the ASR potential of aggregates; this work was continued by a doctoral student under his supervision at The University of Alabama as her dissertation topic, and provided considerable insight into the mechanisms of ASR at very high temperatures and alkali loadings.

Dr. Giannini also has an interest in the potential of bamboo as a construction material; he has directed research on the mechanical properties of bamboo grown and harvested in the U.S. and coordinated an NSF-funded summer research program for undergraduate students focused on the engineering properties and behavior of bamboo.

Dr. Giannini has a Ph.D. in Civil Engineering from The University of Texas at Austin and is a licensed Professional Engineer in the Commonwealth of Virginia. He also worked on submarine overhaul and repair projects as a Naval Architect for five years at Norfolk Naval Shipyard, focusing on ship stability (weight and moment control) and dry docking operations. He was a key contributor to the success of emergent repair projects following two grounding incidents. He was named an ASCE ExCEEd Teaching Fellow in 2013 (one of 24 early-career faculty in the US that year) and a PCA Educational Foundation Research Fellow in 2010. Dr. Giannini is active in several technical and professional organizations, including the American Concrete Institute (ACI), ASTM International, RILEM, and American Society of Civil Engineers (ASCE). He served as the inaugural chair of the ACI 228-B subcommittee on Visual Inspection from 2012 to 2015.
