Hang graduated in Civil Engineering at Southwest Jiaotong University (SWJTU) in China in 2010, where he focused on Highway Engineering. After that he completed his Masters degree in Bridge & Tunnel Engineering at SWJTU in 2013. Hang was then awarded an MSc degree in Civil and Structural Engineering from the University of Sheffield in 2014. He obtained his PhD from The University of Sheffield in 2018 and the topic of his PhD thesis is ‘Mechanical behaviour of blended SFRC using manufactured and recycled fibres from tyres’. Hang’s main interests are focused on FRC (Fibre Reinforced Concrete) using blends of reused and manufactured steel fibres, free and restrained shrinkage of FRC and crack width control of FRC. He was involved in two collaborative research projects: FP7 European funded “Anagennisi” and Innovate UK ”Clean Steel”.

Recent activities and achievements

Project title: Restrained shrinkage of concrete reinforced with blended fibres.

Objectives: 1. Obtain the mechanical properties of concrete mixes reinforced with different fibre blends (e.g. reused tyre steel fibres) at different dosages. 2. Assess the effect of adding different fibres to control shrinkage induced cracks and evaluate the impact of the cracks on the residual mechanical properties of FRC. 3. Develop restrained shrinkage cracking models based on finite element analysis and experimental results.

Tasks and methodology: The aim of this work is to assess restrained shrinkage cracks in concrete reinforced with different fibre blends at different dosages, using experimental and analytical techniques. The experimental work will include flexural, compressive and restrained shrinkage tests. Finite element analysis software (e.g. ABAQUS) will be used to simulate the cracking behaviour of FRC due to shrinkage and external loading, leading to design oriented equations.

Expected results: 1. Reliable experimental data on the flexural behaviour of FRC reinforced with different fibre blends. 2. Models for the mechanical properties of hybrid FRC. 3. The effect of fibres on restrained shrinkage crack development.

Innovative Use of all Tyre Components in Concrete
Anagennisi: Innovative Use of all Tyre Components in Concrete An estimated one billion tyres are discarded each year. Post-Consumer tyre arisings for EU countries (2010) are 3.4M tonnes per year. At the moment nearly 50% of all recycled tyres/components still end up as fuel, in low grade applications or in...

Clean steel

Clean steel: Re-use of steel cord from tyres as reinforcement in sustainable construction Concept: A method has recently been developed for recovering very high strength steel cord (RTSC) from the significant volumes of pre-vulcanised rubber waste generated during the manufacture of car and truck tyres. Preliminary research has shown this...
