Sažetak
An evolving microstructure while also considering the contribution of the ITZ and air voids and to examine the influence on frost durability. The numerical model is used to visualize this phenomenon and to show the contribution of both the pores and the ITZs to the continuation of capillary pore. Once the capillary pores are blocked by ongoing hydration the transport of harmful dilutions are restricted to move into the microstructure. However, distinction is made between the pore connectivity as developed in the bulk paste and the connectivity as developed by connected ITZs. A blockage of the capillary pores (pore discontinuity) as well as a blockage of the ITZs contribute to an increased depercolation of the cementitious microstructure and improve the microstructural performance. The surface durability of freeze/thaw resistance of pavements and chloride ingress is evaluated in view of the pore continuity modelling approach.
