Abstract: Pore structure of paste, mortar or concrete affects the behaviour of the material and can give insight into both material nanostructure and microstructural and its performance. This investigation was carried out to assess and understand the influence of PFA and SF as a cement replacement on the pore structure of cement mortar. The pore structure study was conducted using mercury intrusion porosimetry on cement mortar incorporating PFA up to 40% and SF 10% as partial cement replacements for the preparation of various combinations of binary and ternary blended systems. Pore size distribution was conducted at various ages in a standard curing environment. It was observed that PFA incorporation has slight pore refinement effect whilst SF inclusion demonstrated significant improvement on pore refinement.
