The standard consistency test is done in a:

🧪 Standard Consistency Test Apparatus

The Vicat’s apparatus is used to determine the standard (normal) consistency of cement paste — the water content at which a standard plunger penetrates 33–35 mm into the paste in 30 seconds. This consistency is then used as the reference for determining setting times (initial and final) using the same apparatus with different needles.

Key takeaway

Vicat = consistency + setting time. Le-Chatelier = soundness. Blaine = fineness. Three different tests, three different instruments.
