Description and Specification for Lab Tenders
Astra Scientific Automatic Vicat Apparatus.
General Description:
have long tradition in manufacturing automatic setting time
testers for cement and mortar. A new generation, the third one, is now
available. The new machine has been completely redesigned based on the
innovative CVI-TECH philosophy. As with the older generations the test
procedure is unchanged, a needle (or a probe) drops freely into a cement
sample at regular intervals and in fixed positions. Penetration depth
is measured by a sensor with 0,1 mm resolution. Along with hardening
process development the penetration depth decreases, when it matches
some thresholds pre-defined by Standards initial and final setting times
are measured and recorded.
