To measure the axial and/or superficial dimensional shrinkage of
concrete specimens during hardening process in a curing room.
STANDARDS: UNI 11307 | UNI 6555 (comparable to ASTM C426)
The specimen is prepared by a mould having dimensions
100x100x500 mm, with aggregates up to 30 mm max. diameter,
and after housed in the measuring apparatus that determines the
axial shrinkage.
The two UNI Standards require two different systems to prepare the
specimen:
– The UNI 11307 requires reference pins to be sticked on the
specimen.
– The UNI 6555 requires inserts fixed into the mould and let into the
specimen.
