Expertise: Structures and Materials
1. Structural resilience;
2. Concrete engineering and technology;
3. Sustainable infrastructure; and
4. Structural repair/rehabilitation.
My present research efforts in the area of concrete engineering and technology are mainly focused in two niches, namely on the synthesis and development of an enhanced version of hybrid-fiber-ed ultra-high-performance cementitious composites (UHPCC), and on the optimized utilization of industrial and agricultural by-products in concrete production. In the former, my group has successfully synthesized a unique blended hybrid-fiber-ed cementitious composite system with carbon nanotubes and steel micro-fibers, which exhibits excellent ductility and post-crack characteristics. On the latter, I have been working on optimizing the combined utilization of industrial by-products (silica fume and fly ash), or agricultural waste (rice husk ash and palm-oil fuel ash), with alternative aggregates from industrial waste (quarry waste and waste glass) as alternative concreting materials. I have collaborated productively for many years with Professor Md. Safiuddin of George Brown College, Canada, and have accomplished some meaningful output in this area. The outcome from these research efforts converge towards the design and development of more resilient structural materials, which contribute towards the overall sustainability and safety in the built environment.
Meanwhile, in the area of structural resilience, my work is directed towards the development of new strategies in design, construction and retrofitting of infrastructure to enhance their sustainability and safety against extreme loading and climatic events. The main work of my group has been towards the development of a novel technique of using sustainable bio-based elastomeric polymers to enhance the structural capacity and energy absorption characteristics of structures against extreme impulsive loadings of blast, ballistic and impact. I have collaborated successfully with the group of Profesor Khairiah Badri (of UKM), Professor Priyan Mendis (at The University of Melbourne) and Dr. Damith Mohotti (at The University of Sydney) in this area.
I have consistently been able to attract competitive grants and funding from various bodies, including Malaysian Government agencies, as well as multi-national industries. These amounted to more than MYR$4.0mil throughout my career.
