Trenchless Technology Center

Material Science Research

Research in geopolymers and other cementitious materials has been conducted at the Trenchless Technology Center (TTC) since 2006. Team expertise in this field can be assessed by numerous publications including peer reviewed journals, articles in Underground Construction, patents, presentations in conferences, etc.

The research activities in this area include forensic materials evaluations of chemical grouts, polymers, metals and other materials used in buried infrastructure, characterization and determination of failure modes and damages due to corrosion and weathering. TTC’s laboratory has capabilities to perform optical metallography, scanning electron microscopy (SEM), quantitative microstructural analyses, scale and deposit analyses for corrosion evaluations, chemical composition analyses and alloy verification, and mechanical testing.

TTC’s materials science research is supported by partnership with the Institute for Micromanufacturing (IfM) at Louisiana Tech, which hosts some of the high technology equipment, such as that shown in the table and picture below.
