About RMTI

Contact UsLinks and ResourcesResource Materials Testing, Inc. (RMTI) was founded by Dr. Robert Smith in November of 1988 to test by-product materials, such as coal fly and bottom ash, slag, kiln dust and silica fume, as well as natural pozzolans.  These materials are used in construction and typically require testing for ASTM (American Association for Testing Materials), AASHTO (American Association of State Highway Officials), and other specifications for quality and consistency. 
RMTI is an AASHTO Accredited, independent testing laboratory that is routinely inspected by Cement and Concrete Reference Laboratory (CCRL) personnel for pozzolans and participates in the CCRL pozzolan proficiency program. Our typical clients include ash marketers, utilities, and by-product (Kiln dust and FBC) marketers, but we welcome all opportunities.
