Research topics
Dr. Nguyen is focusing to develop new construction building materials which have much potential on mechanical properties, autogenous healing ability, and sustainability. Herein, he would mention some major research topics that he has done and have been deploying
Research Topic 01
Autogenous healing of engineered cementitious composites (ECC)
This research presents an experimental investigation on autogenous healing of high-performance engineered cementitious composites with compressive strength over 90 MPa and tensile strain capacity over 4.5% using different amounts of calcium-containing binders
Research Topic 03
Ultra-high-ductile alkali-activated slag composites
This research experimentally investigated the mechanical properties of eco-friendly ultra-high-ductile fiber-reinforced slag-based composites. The designed composites showed a very high tensile strain capacity over 8% and a tensile strength around 10 MPa
Research Topic 04
Ultra-high ductile engineered geopolymer composites
This research introduces ultra-ductile fly ash-based engineered geopolymer composites. The mixture using an SMP/SH (sodium metasilicate pentahydrate-to-sodium hydroxide) ratio of 1.5 achieved a tensile strain capacity of 13.7% and a tensile strength of 6.8 MPa. Moreover, all mixtures were lightweight, with density below 1.83 g/cm3
Research Topic 05
Sustainable and highly ductile rubberized composites
This research investigated the effect of the addition of crumb rubber particles on the mechanical properties and sustainability of alkali-activated slag composites reinforced by polyethylene fiber. The test results showed that the composites achieved the strain-hardening behavior with a superior tensile strain capacity over 10% and sustainable potential
Research Topic 06
Impact resistance of a hybrid structure using ultra high performance concrete and high ductile composite
A series of experiments including static loading tests and high-velocity projectile impact load tests was performed. From the test results, it was found that the hybrid layered panels, in which a high-strength composite was located at the front side and a high-ductility composite was located at the rear side, had impact resistance higher than those of other panels
Research Topic 07
Development of extremely ductile slag composite with a tensile strain capacity up to 22%
In this research, the feasibility of developing extremely-ductile alkali-activated slag-based composite (ED-AASC) with a tensile strain capacity over 20% is presented. Specimens with a moderate amount of sand and crumb rubber particles were made by applying new mixing and curing procedures.
Research Topic 08
Matrix designs of ultra-ductile engineered geopolymer composites
Three key factors, i.e., curing temperature, curing time, and fiber volume, were investigated to determine their prominent effects on the density, compressive strength, and tensile properties of the engineered geopolymer composites using the Taguchi robust design method.
Research Topic 09
Development of high-performance engineered geopolymer composites with their functional abilities
Research Topic 10
Development of sustainable and resilient ductile composites using short selvedge fibers
