Abstract

The presented experimental investigation forms part of a wider research programme directed to explore the microstructural properties of cementitious composites with improved resistance to freezing and thawing. A series of airentrained mortars were subjected to alternating environmental conditions over a prolonged period of time. Significant alterations at the microstructural level resulting from the exposure to 480 cycles of freezing and thawing (F/T) were examined by means of the Mercury Intrusion Porosimeter (MIP) and the Scanning Electron Microscope (SEM). The pore size distribution gave evidence of the dominating range of pores being shifted towards the higher values of pore diam
