Dr. Pacheco has expertise in the development of high performance and conventional concrete mixtures for construction; construction troubleshooting; assessment and evaluation of concrete degradation mechanisms; and service life predictions for new and existing concrete structures. His other areas of technical work include moisture and transport properties of concrete, volumetric changes of concrete (creep & shrinkage), internal curing, and advanced characterization techniques. Dr. Pacheco specializes in providing solutions for asset owners, engineering firms, and contractors on several subjects including the selection and evaluation of construction materials, construction troubleshooting, durability performance of existing concrete and steel structures, and the selection of repair and mitigation techniques for extending service life.
Prior to working at CTLGroup, Dr. Pacheco worked at the Dutch Institute of Applied Sciences (TNO) in the Netherlands as a consultant on civil engineering projects. His work focused on concrete durability and degradation, concrete materials evaluation, and concrete repair.
