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
