Vicat 一致性 Tester

牧师器具测验

One of the most common ways to assess cement consistency is with a Vicat apparatus. This machine is used to determine the st和ard consistency of a cement paste, as well as its initial 和 final setting time.

To establish a paste’s st和ard consistency, a Vicat plunger is used. St和ard consistency is defined by the minimum amount of water at which the Vicat plunger is able to penetrate 5-7mm from the bottom of the Vicat mold. This consistency, in theory, will produce cement at its maximum strength.

To establish a paste’s initial 和 final setting times, a Vicat needle is used. The initial setting time is defined as the time period between when water is added to the cement 和 when the 1mm needle fails to penetrate the paste. 最终凝固时间, 而, is determined by the time period between when water is added to the cement 和 when the 1mm needle makes an impression on the paste but the 5mm needle does not.

The plunger 和 needle apparatus tests are used together to ensure effective cement which in turn will produce good quality concrete. 洪堡 offers a variety of products for performing Vicat apparatus tests:
