Bud Werner, CTL | Thompson Principal Engineer, will discuss the history of damage to concrete due to expansive reactions caused by internal alkali and reactive aggregates. He will describe the evolution of the testing methods used to predict performance and to verify mitigative ability of combinations of materials when reactive aggreagtes are used. He will discuss the improvements and the difficulties that have been created by ASTM C1778, "Standard Guide for Reducting the Risk of Deleterious Alkali - Aggregate Reaction in Concrete."

Orville (Bud) Werner is a senior principal engineer with CTL | Thompson. He has more than 45 years of experience in the technology of concrete construction. He specializes in materials testing, testing oversight and consultation, performance analysis, and design and production of concrete materials. Bud joined CTL | Thomspon in 1983. He led CTL's materials testing laboratory for 20 plus years and manages CTL's materials testing. Bud has nearly 50 years of experience investigating concrete durability and strength, specializing in the physical and chemical characteristics of concrete and concrete materials with particular expertise in the testing and inspection procedures for cement and fly ash, pozzolans and aggregate materials. In the field and in the lab, Bud identifies the mechanisms of deterioration, predicts future performance and recommends mitigative measures to incraese the life of concrete in sturctures and pavements.

Mr. Werner is known nationally and internationally for his highly specialized experience and ability to generate solutions for themost complex materials design. He is a Fellow of the American Concrete Institute, a Past-President of the Rocky Mountain Chapter of ACI, and a 40 year member of both the American Concrete Instiute and the American Society fo Testing and Materials (ASTM).
