Alkali-silica reaction (ASR) is a chemical reaction between siliceous minerals present in certain aggregates and alkalis in the concrete pore solution. The reaction can lead to expansion and severe damage in concrete members. One method to mitigate ASR expansion is to use a penetrating sealer such as silane. A set of columns located in a food preparation facility was treated with silane and a complimentary laboratory study was performed. A cleaning regimen involving application of an alkaline cleaner is employed at the facility, followed by rinsing with hot, pressurized water. The purpose of this research is to evaluate the effectiveness of silane when used in this alkaline environment. The research shows that silane was effective at reducing expansion in new concrete, less so when the pH of the environment is high; other measures were recommended for previously cracked concrete. I would like to thank Steve Avair of Ecolab for his help donating the cleaner used in this study. I want to thank Gary Cox, Lance Logsdon, Mike Davis, and Seth Walters for arranging and implementing our study at their facility. This project taught me about the importance of industry in supporting academia and the advancement of knowledge. Also, I would like to thank Kyle Niemann in particular, for showing us around and being available to us when we visited the facility. I would like to thank Richard Deschenes, who has been a tremendous help for me through all of the work I have completed at the University of Arkansas, including frequent trips to the facility for measurements. Richard has also challenged me intellectually, both in my classes and research work, and has been an excellent peer. I have learned a lot from his devotion and he has made a major contribution to my work and my understanding of ASR. I would also like to thank Casey Jones for his help in the earliest stages of this work. I would like to thank the Department of Civil Engineering at the University of Arkansas, in particular my thesis committee; this group has impacted my education and my decision to continue graduate education. I would like to thank Dr. Micah Hale, I am not sure what I would be doing now if it weren't for his impact in my life, but I am quite sure I would not be completing a Master's Degree. He has been instrumental in my decision to become an academician. I look forward to a continuing personal and professional relationship with him for years to come. Finally I must thank my loving parents David and Kathryn. They are a source of unending inspiration to me, and I owe more to them than I could put into words.
