Rapid Chloride Permeability Test (RCPT) Equipment

Procurement Summary

The National Institute of Standards and Technology (NIST) Engineering Laboratory (EL) Materials and Structural Systems Division (MSSD) studies the durability and service life of infrastructure materials (polymers, concrete, engineered composites, etc.) for resilient infrastructure applications. One of the key research focuses is to evaluate the durability of these materials to environmental factors that could expedite deterioration. One such environmental factor that can impact the long-term structural integrity of concrete structures is exposure to chloride ions (Cl-). The MSSD will benefit from rapid chloride permeability test (RPCT) equipment to evaluate concrete materials in the “Engineered Materials for Resilient Infrastructure” program in projects such as “Assessing Pyrrhotite in Concrete”, “Forward Looking Building Codes”, and “Additive Manufacturing with Cement Based Materials” as well as Disaster and Failure program investigations such as the investigation into the collapse of the Champlain Towers South condominium building.
