Test devices for cement,gypsum and lime

Le Chatelier Water Bath Free LimeDetermination Device

Device to determine the stability of cement which may change when expanding during hydration. For this purpose up to 16 specimen bars can be stored in a bath of boiling water or water vapor. The heating cycle – e.g. heating up to 100ºC within 30 min and keeping this temperature constant for more than 3 h – is regulated automatically and with a high accuracy (accurate to 0.1ºC). Setting time and setting temperature may vary according to the requirements in question.Easy and industrial safe handling.

Automatic VICATNeedle Apparatus

Device to determine theconcentration of free lime in cement or cement clinker. For this purpose the conductivity of a cement solution in hot glycol is measured.The menu-guided test sequenceallows an easy and safe handling and short test times. The test results are available more quickly compared to other methods, thus allowing also a quicker correction of the industrial furnace operation and the burning process. Apparatus to determine the settingtime on up to 8 specimens irre- spective from each other. The time of begin and end of the setting process of cement, gypsum or mortar is measured. The penetration depth of the Vicat industrial needle into the specimen is measured, evaluated and saved according to 3 different methods. The measurements may be carried out in any order at any of the 8 available spots thus making optimum use of the specimen surface but considering the conditions set by the different standards.

Automatic Blaine Apparatus

Apparatus to determine the specificsurface of cement and other powdered materials. The time required by a certain air volume to penetrate a powder bed is measured in accordance with EN 196-6. Measurement, test sequence control and evaluation are automatically performed.
