About the Speaker:
Bruce Collins holds a Bachelor of Science degree in Chemical Engineering with a minor in Economics from the Colorado School of Mines, Golden Colorado. He was elected to the National Board of Directors, International Concrete Repair Institute in 1997 and served until 2008. He was voted an ICRI “Fellow” in 2002. He worked on numerous ICRI guidelines including Hydrodemoltion, Pull-off Bond Testing, Selection of Strengthening Systems and Post Tension Repair. He was a voting member of the ICRI Technical Activities Committee for 6 years. At The American Concrete Institute, Mr. Collins is a voting member on ACI Committee 364 “Rehabilitation of Concrete Structure” and has been a professional speaker for ACI Concrete Repair Basics and ACI Concrete Repair Workshops.
Bruce Collins has published project papers in Engineering News Record, Parking Magazine, The Concrete Repair Bulletin and Power Magazines, PTI Journal and has presented project papers at SSPC, ICRI and ACI National Conventions.
Have you ever wondered if your concrete repair is properly installed and/or whether it is performing as intended? Testing prior to and/or after completion of repairs can help determine if repairs are successful. This presentation will review case study examples of repair work to show standard testing methods being used to measure the success in concrete repair projects.
Three case studies will be presented and include the following:
1. Deterioration of a cooling tower due to concrete corrosion. Corrosion rate measurements are used prior to and after repairs to understand the success of the repairs.
2. Corrosion of concrete reinforcing in foundation walls of utility tunnels due to water infiltration. Concrete resistance testing is used to measure the success of curtain wall grouting repairs.
3. Various examples of tensile bond pull-off testing including a folded roof plate slab and a water treatment tank to test the success of concrete repairs using Hydrodemoltion and jack hammering for concrete surface preparation.
Whether or not you are familiar with these test methods, this lunch presentation will provide a good opportunity to see them used and/or to simply ask questions about them.
