Structural Engineering, Concrete Technology


Establishing a well-founded academic career focused on research and development of innovative civil engineering materials and composites. The research focuses on rheological characteristics and physical and chemical properties of cement-based materials that are needed to enhance quality, aesthetics, structural performance, and service life of concrete structures and facilitate concrete placement operations with correlation to production and processing, structural performance, durability, and service life. Also interested in developing strong expertise in the area of rehabilitation of concrete infrastructure and environmental issues concerning the performance and use of industrial by-products in cement-based materials.



Research experience dealing mainly with the formulation and development of high-performance cement-based materials for structural applications and rehabilitation as well as the use of fundamentals of materials science and engineering, including rheology, physical chemistry, and microstructure to develop cost-effective, innovative materials for the construction and rehabilitation of civil engineering structures.

Recent research has concentrated on developing Q/C testing methodology for design and control of specialty materials, including post-tensioning grout, underwater concrete, and self-consolidating concrete (SCC). This includes the development of instrumentation and protocols to monitor in-situ variations in homogeneity of plastic material. This method is unique and enables the monitoring on a continuous basis of internal bleeding. Recent research has also aimed at understanding the effects of supplementary cementitious materials, fillers, and rheology-modifiers on segregation resistance, mechanical properties, and corrosion resistance of flowable concrete. Proposed ternary cements have led to the introduction of new specialty cements on the Canadian market. Findings involving the influence of concrete composition and properties on structural performance, stability of entrained air, corrosion behavior, bond to embedded reinforcement, and mechanical properties have been essential to the engineering community in embracing SCC in repair applications and for the construction of structural elements of complex sections. Efforts are also made to further the use of SCC in the precast, prestressed industries, which has been to date very successful in the U.S.A.

Significant research has concentrated on understanding the influence of material constituents, mixture proportioning, specialty chemical admixtures, and adverse placement conditions on performance of underwater concrete. Advances in this multi-disciplinary field have made it possible to cast shallow lifts of concrete in water for repair, more flexibility in positioning and movement of placement devices, lower level of pollution, and greater service life. Recommendations stemming from this research have served for major projects, such as the backfill of tunnel lining in the Channel Tunnel in Europe, the foundation of the Confederation Bridge, the construction of pile caps for a water intake structure in Florida, and the repair of damaged bridges (Champlain Bridge, Victoria Bridge, St. Lambert Lock).
