TESTING OF HARDENED CONCRETE HYDRAULIC SHRINKAGE DETERMINATION

Category:

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.
EQUIPMENT ACCORDING TO UNI 11307:
C254-01
BEAM MOULD, steel made, to prepare a concrete specimen
100x100x500 mm
Weight: 23 kg approx.
C366-12
REFERENCE PIN, to be sticked in
the intersection of the longitudinal axis
of the specimen with its bases.
Pack of 10

EQUIPMENT ACCORDING TO UNI 6555
(comparable to ASTM C426):
C365
SHRINKAGE MOULD, steel made, complete with inserts, to
prepare a concrete beam specimen 100x100x500 mm
Weight: 23 kg approx.
C366-11
INSERTS, stainless steel, spares to C365 mould. Pack of 10

NEEDED ACCESSORIES, ACCORDING TO:
UNI 11307 AND UNI 6555

complete with reference bar, but without dial gauge to
be ordered separately. Weight: 23 kg approx.
S375 DIAL GAUGE, 5 mm stroke by 0.001 mm sens.
AS AN ALTERNATIVE:
S376 DIAL GAUGE, 10 mm stroke by 0.01 mm sens.

0.001 mm) and in inch (sens. 0.0001”), battery feeded.
Complete with battery and RS232 connector to PC.
S382-13 CABLE to connect S382-01 and S383 to PC through
USB port for direct visualization and recording of the
measurement.
