By automating the traditional Vicat penetration method, the system provides controlled testing and reduces the subjectivity associated with manual penetration measurements.\u003c\/p\u003e\n\u003cp\u003eThe testing principle is based on monitoring the increasing resistance of cement paste as it changes from a fresh, workable material to a progressively stiffer and hardened state. A standardized 300 g sliding assembly with a testing needle is positioned above the fresh cement paste. During the early stage of testing, the needle penetrates deeply into the specimen. As hydration progresses, the paste develops greater resistance to penetration, resulting in progressively shallower penetration depths.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eInitial Setting Time: The point at which the cement paste has stiffened sufficiently that the standardized needle no longer penetrates to the bottom of the test mold.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFinal Setting Time: The point at which the paste has hardened sufficiently that the needle produces only a slight indentation on the specimen surface.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe QualiVicat™ II monitors penetration depth at defined time intervals and records the change in vertical displacement throughout the test.
