The spatial distribution of moisture in concrete, along with the role
this moisture plays in various modes of deterioration, is of fundament
al importance to the understanding of concrete behaviour. In this pape
r a new magnetic resonance imaging technique is utilized for the first
time to obtain drying profiles of concrete with sub-millimetre resolu
tion. This technique permits observation of the drying mechanisms, as
well as the effects of water-cement ratio and moist curing time on dry
ing behaviour. (C) 1998 Elsevier Science Ltd.
