This study reviews the accuracy of the conventional concrete (CC) shrinkage prediction models proposed by the international codes of practice, including CEB-FIP (1990), ACI 209R (1997), Eurocode 2 (2001), JSCE (2002), AASHTO (2004; 2007) and AS 3600 (2009).
Also, SCC shrinkage prediction models proposed by Poppe and De Schutter (2005), Larson (2007), Cordoba (2007) and Khayat and Long (2010) are reviewed.
He has advised more than 60 masters and doctoral students.
He has conducted sponsored researches on many aspects of prestressed and reinforced concrete, including torsion and shear, bond and development length, loss of prestress, applications of high performance and high strength concrete, self-consolidating concrete, jointless bridge deck, and cracking in large prestressed concrete girders.

His studies also included fatigue strength of cracked prestressed concrete girders, assessment of high performance concrete bridges, development of a non-destructive test method for measuring air permeability of concrete, the use of self-consolidating concrete in highway structures, and application of corrosion-resistant high-strength MMFX steel for concrete structures, and structural applications of new proprietary materials called Grancrete and Elimix Admixture. Zia is a registered professional engineer in North Carolina and an honorary member of both American Concrete Institute (ACI) and American Society of Civil Engineers (ASCE), and a Fellow of Precast/Prestressed Concrete Institute (PCI).
He has served as chairman and member of many technical and administrative committees of these organizations, including a term as President of ACI in 1989-1990.
Self-compacting concrete (SCC) contains combinations of various components, such as aggregate, cement, superplasticizer, water-reducing agent and other ingredients which affect the properties of the SCC including shrinkage.
Hence, the realistic prediction shrinkage strains of SCC are an important requirement of the design process for this type of concrete structures.
