techniques developed to improve understanding of the
early-life behaviour of concrete industrial ground-floor
slabs. Concrete strains, temperatures and joint
movements were measured using vibrating-wire
embedment strain gauges and thermistors, while
ambient conditions were monitored to assess their
effects. A reliable, accurate and easy-to-implement
methodology, developed by instrumenting four types of
floor slab (mesh-reinforced long strip, mesh-reinforced
jointed large area pour, steel fibre-reinforced jointed
large area pour and steel fibre-reinforced jointless large
area pour) is described in detail, along with the further
developments and modifications to the instrumentation.
The methodology developed would be equally applicable
to the early-life monitoring of other concrete structural
elements. Some sample results of data gathered using
the instrumentation methodology developed are
included.
