Abstract: Internal curing of high performance concrete (HPC) by either pre-saturated lightweight aggregates or super-absorbent polymers is a well established method of counteracting selfdesiccation and autogenous shrinkage. However, by introducing the internal water reservoirs strength and durability properties can be injured. Tests for the wide accepted methods of durability assessment, such as resistance to chloride penetration, air permeability, water absorption, drying shrinkage and mass loss, were conducted on HPC mixes made at water to cement ratios in the range of 0.21- 0.33. The effect of internal curing on the durability related properties of high-performance concretes as a function of water to cement ratio is reported.
