This document describes a test conducted to determine the normal consistency of a hydraulic cement. The objective is to find the amount of water needed to create a cement paste of a certain standard thickness. The test procedure involves mixing cement with varying amounts of water and using a Vicat apparatus to measure when a plunger settles 10±1mm below the original surface of the paste within 30 seconds. The percentage of water that produces a paste with this consistency is considered the normal consistency and is used to standardize mixtures for other cement tests.
