Aziz Hasan Mahmood is a PhD candidate at the school of Civil and Environmental Engineering, University of New South Wales (UNSW). He has been awarded the Tuition Fee Scholarship from the same school for his PhD candidature. Prior to joining UNSW, Aziz received his MS and BS in Civil Engineering from Islamic University of Technology (IUT), Bangladesh, in 2015 and 2012 respectively. He worked as a lecturer in the department of Civil and Environmental Engineering (CEE), IUT for 3 years. Besides academic duties, Aziz was active in commercial testing of materials.

Currently, Aziz is investigating the possibility of utilizing steel furnace slag aggregate geopolymer concrete in coastal breakwaters. Breakwaters are coastal structures that protect harbours and coast from wave action by breaking waves and dissipating energy. Though breakwater building units, known as the breakwater armours are conventionally made with quarried rocks, difficulties associated with quarrying has led to concrete armour units in recent years. Since these armours need to be heavy as the armour unit size is a cubic function of the wave height, use of heavy steel furnace slag (SFS) aggregate, a by-product of steel making industry, can be a promising concept in making concrete armour units. However, SFS aggregates contain free lime, which, when hydrated, expands and simultaneously threatens concrete durability. SFS aggregates can be used in geopolymer concrete with low calcium content to investigate whether it affects the free lime. The aim of this research is to explore the possibility of using SFS aggregate in geopolymer concrete. Concrete will be tested for both fresh and hardened properties. Fresh geopolymer concrete is viscous and often hampers the overall construction. This research will also address workability and setting time of geopolymer concrete. Moreover, strength durability of SFS aggregate made geopolymer concrete will also be studied for coastal breakwater applications. The armour units will also be modelled for finite element analysis to justify it’s strength in withstanding wave forces.
