N2 - It is generally accepted that when considering relationships between microstructure, mechanical properties and durability performance, the most significant microstructural component of concrete is the pore structure. To better understand how material composition and microstructrural modifications determine the high strength concrete structrural performance, the relationships between porosity and different engineering properties including compressive strength, conductivity, autogenous and total shrinkage were evaluated. This paper illustrates the effect of silica fume, ultra fine fly ash and ground granulated blast furnace slag on the porosity, strength and conductivity of high strength-high performance concrete, and investigates the shrinkage behavior and cracking potential of these high performance mixes. The drawn correlations between porosity, conductivity and shrinkage indicate that optimizing the microstructure can be used to improve autogenous shrinkage and minimize shrinkage cracking without affecting mechanical and durability properties.
