Laboratory Manager | Materials Laboratory Services
Dr. Bentivegna specializes in the characterization and implementation of cementitious materials and the mitigation of premature deterioration due to concrete durability problems. Additionally, he is an expert in the investigation and mitigation of structures affected by alkali-silica reaction (ASR) and in the development and implementation of rapid repair cementitious systems, including calcium aluminate cement (CAC).
Dr. Bentivegna also has extensive knowledge in the development of concrete testing. He developed his own testing apparatuses for monitoring cement hydration, including isothermal calorimeters and chemical shrinkage setups, as well as techniques for monitoring early-age volume change. These testing setups aim to more accurately correlate laboratory testing to actual field performance.
As a graduate research assistant at the University of Texas, Dr. Bentivegna participated in concrete-related projects with emphasis in fly ash, calcium aluminate cements and lithium implementation for ASR-affected concrete. He performed this work for the Federal Highway Administration, local department of transportation offices, international companies and local businesses. Dr. Bentivegna also has experience in structural and transportation engineering, having worked as an intern at design consulting firms.
