Incorporation of Metal-Laden Granular Activated Carbon in Concrete Formulations
Full Project Title: Industrial Trial with Forterra for the Incorporation of Metal-Laden Granular Activated Carbon in Concrete Formulations for the Inhibition of Biogenic Corrosion in Concrete Sewer Pipelines
Participants: Prof. Mark T. Hernandez, Prof. Wil Srubar III, Ismael Justo-Reinoso, Alejandro Caicedo-Ramirez and Forterra personnel
Primary Investigator: Prof. Mark T. Hernandez
Summary: A new generation of smart product formulations has been developed for the inhibition of biogenic corrosion for piping systems where extreme corrosion rates have been historically observed. Granular activated carbon loaded with heavy metals is used as an admixture in concrete and cement mortars formulations for the inhibition of microbially induced concrete corrosion (MICC). The principal objective of this project is to translate the already successful obtained laboratory results to a practice in an industrial trial jointly with Forterra, which is an international company that is dedicated to the fabrication of concrete sewer pipelines and manholes.
Materials previously weighed in the laboratory and ready for the elaboration of four concrete formulations
