Dr Li Zheng

Dr Li Zheng is a graduate of Civil Engineering at Southeast University, China (1982) and completed his Master Degree in 1984. Joined the Concrete Technology Unit team as a Research Assistant in 1996, he completed his PhD study in CTU in 2001 and has been working as a research fellow since then.

Dr Zheng has been involved in several research projects in the concrete research area, including:

* Regulated Dangerous Substances of Aggregates  (2007-2008)

* Cement Combination Project (2006-2009)

* Optimisation of Concrete for Durability in Different Exposure Conditions (1997-2002)

* Design Data for Low Heat and Very Low Heat Special Cements (2001-2006)

* Increasing the Use of Foamed Concrete Incorporating Recycled and Secondary Aggregates (2005-2007)

* Recovery and Beneficiation of Stockpiled and Landfilled Fly Ash for Use in Construction (2004-2008).

His work is concerned with concrete durability, optimisation of materials to enhance concrete performance and mathematical modelling of particle packing and concrete durability performance. Several computer software were developed during his research work, such as particle packing calculation, concrete mix design/ optimisation and early age concrete temperature prediction, which are beneficial and can be well used in the industry application. His recent work mainly focuses on using recycled materials in construction, which is an important issue for our environment conservation and sustainable development.

Prior to joining the CTU, he had worked in Building Materials Unit, Zhejiang University for 12 years and completed a number of research projects including fly ash autoclaved aerated concrete, non-destructive tests of concrete, alunite self-stressing/expanding concrete, constitutive relation of concrete for dam analysis, and evaluation and treatment of the cracks in dam, etc.
