Category:

E067-05
MORTAR BAR CONTAINER
STANDARDS: ASTM C227, C1260, C1567 | UNI 8520-22
This test method covers the determination of the potential alkali
reactivity of cement-aggregate combinations (mortar bar method).
The device is composd by an acrilic cylinder container with a stainless
steel rack.
Dimensions: Ø 170 mm x 450 mm
Weight: 3 kg approx.
Note: Prism moulds, length comparator and accessories:

MORTAR WORKABILITY APPARATUS
STANDARDS: EN 413-2 | NF P18-452
Designed to test concrete mortar for dynamic workability and also to
ensure optimum proportioning of mortar constituents (sand, water,
cement, as well as cement/sand and water/cement ratios) compatible
with given application. Suitable also for checking possible
improvement when admixing a plastifier, or for comparing two mortar
types. The unit consists of a prismatic receiver divided into two unequal
volumes by a removable partition, and by an electric vibrator.
The fresh mortar is poured in the large volume place, the separating
partition is removed and the vibrator stats automatically. As a result
of vibrations, mortar flows from the large volume to the small one, in
a time which is a function of the workability of the mortar.
Power supply: 230V 1ph 50Hz 110W
Dimensions: 400x200x200 mm
Weight: 18 kg approx.
