Our heartiest congratulations to 3 CEE research fellows Dr. Padmaja Krishnan, Mr. Gilbert Sebastiano and Dr. Lai Binglin for being awarded the top two prizes in the American Concrete Institute-Singapore Chapter (ACI-SC) Annual Project Competition 2020. They were supervised by Prof Richard Liew.
Dr. Lai Binglin received the Gold Prize (1st prize. His topic was “A novel and sustainable partially precast composite column using high strength and high ductility concrete materials”. The study proposed a novel SRC composite column by employing advanced new materials and precast technology as an alternative for conventional cast-in-situ high strength SRC column, which overcome the inherent brittleness of high strength concrete and expedite the construction process.
Dr. Padmaja Krishnan and Mr. Gilbert Sebastiano received the Silver Prize (2nd prize). Their topic was “Novel lightweight cementitious materials for prefabricated prefinished volumetric construction (PPVC)”. The study examined the possibility of using lightweight cementitious composites (LCC) and steel fibers to replace conventional reinforced concrete and facilitate increased productivity and time savings. The results indicate that adopting LCC can reduce the weight by 23% while the durability properties of LCC and normal weight concrete are comparable. Further, 1.0% steel fibers (by volume of normal weight concrete) was found to be sufficient to completely replace rebars and satisfy the serviceability and ultimate limit states in typical residential PPVC slabs.
