Durability of concrete made with portland cement and alternative
binders, NSERC Discovery Grant Since joining the
research group in 2013, I am working on a variety of concrete topics,
including an investigation of alternatives to Niagara Escarpment sourced
aggregate for the Greater Toronto Area, an investigation of the expansive
alkali-silica reaction potential of recycled fibre reinforced polymers in
concrete, a project on the effects of using two types of Nano-sized additives
on the fresh and hardened properties of SCC concrete, a project on the CO2
absorption capacity of construction blocks, and the production of a
functional concrete electric guitar. My primary interest is to develop and
refine new approaches to investigate three deterioration mechanisms (i.e.
external sulfate attack, alkali silica reaction, and chloride ingress) from a
microstructural perspective within the context of portland cement concrete
and alkali activated slag, fly ash, and metakaolin concrete mixtures. ·

In our labs, we provide many materials testing
services including: ü Petrographic
examinations of construction materials; ü Standard
and large size petrographic polished thin section preparation; ü Concrete
and mortar failure analysis (at macro and micro scale); ü SEM, XRD,
and micro-XRF analyses; ü Characterization
of materials in historical buildings; ü Automated
air void analysis of hardened concrete; ü Chloride
profiling and other wet-chemical analyses; ü Design of
high performance concrete mixtures; |
