Device for the standard-compliant testing of the expansion of Le Chatelier moulds without permanent deformation (resilience) according to EN 196-3. The device consists of a solid base plate onto that a stand is mounted. The stand has a clamping device to clamp the Le Chatelier moulds and has an adjustable scale to measure the expansion of the mould. A weight and a key ring chain with a total mass of 300 g are part of the delivery. Key benefits for the user: ✓ Adjustable scale for the adaption to the indicator needles ✓ Easy, user-friendly handling ✓ Solid design made of aluminum -
The FLA1 is developed for the determination of the content of free, uncombined lime in cement and cement clinkers. The function principle is based on the measurement of the electric conductivity of a cement solution in hot glycol compared with calibration curves, determined with a two or multipoints calibration curve with reference material.
Benefits:
✓ measurement results in less than 10 minutes possible (typical 15-20 min) ✓ very few preparation time for the user ✓ no activities from the operator are necessary during the measurement procedure ✓ integrated data base with all needed test parameters and intelligent menu guiding ✓ beaker made of stainless steel for easy cleaning ✓ automatic washing cycle as well as optimal ergonomic design of the instrument allows a work fow without interruption ✓ the magnetic agitator is resistant against dust, abrasion and steam of glycol ✓ intelligent system equipped with microprocessor ✓ printer connection for direct output of the results ✓ PC connection for setting parameters and evaluation of the results via the interfaces RS232 and RS485 -
Application The Le Chatelier water bath allows a controlled boiling of cement samples using Le Chatelier moulds (needles). The soundness test is used to determine the possible risk of delayed expansion of cement due to hydration. The water bath corresponds exactly to the requirements of the standard EN 196-3 and performs an autonomous and controlled test cycle. Key benefits for the user: ✓ fully automatic test cycles with parameters for different requirements ✓ after sample preparation, the instrument works without any operator interference until the end of the cycle ✓ controlled autonomous test procedure for accurate reproducible test conditions ✓ designed for easy maintenance and cleaning ✓ integrated water outlet for a quick change of the water ✓ the test cycle can be performed using water or steam ✓ continuous indication of the actual temperature for visual check ✓ heating up from 20°C to boiling temperature within 30 min ± 5 min ✓ stable temperature at boiling conditions during three hours ✓ strengthened insulation; the outer walls of the water bath remain cold ✓ evaporation is limited due to a precise temperature regulation -
Application PC controlled Vicat instrument with eight stations for the determination of the setting time of cement according to EN 196-3 or gypsum according to EN 13279-2. The initial and final setting time are calculated. Key benefits for the user: ✓ tests can be started in any order and at the desired time; the machine performs the measurements independently after placing the samples ✓ measurements are performed according to a preprogrammed penetration grid in order to use the overall sample surface corresponding to the appropriate standard ✓ the results and the corresponding parameters are stored in a data base ✓ automatic backup procedure for running tests ✓ different operator levels protected by passwords allow a very safe handling of the instrument ✓ user friendly software with integrated help menu ✓ predefined standard tests to avoid time-consuming and continual parameter setting ✓ high reproducibility of the measurements ✓ automatic water cleaning of the needle ✓ designed for easy maintenance and cleaning ✓ special mode (password protected) for the calibration of the instrument by the user ✓ integrated menu for automatic tests and checking of the main functions of the instrument -
Application Microprocessor controlled Vicat instrument with one or two test stations for the determination of the setting time of cement, gypsum or mortar according to EN 196 part 3, ASTM C191, EN 13279 or EN 480. Benefits ✓ 5.7“ colour display ✓ Automatic test procedure, including needle cleaning after each penetration ✓ Graphical or table display showing complete setting time procedure (beginning and end) ✓ Very accurate measurement of the penetration depth by an incremental system ✓ Possibility to test under water as according to EN standard or without water ✓ Internal control of the water temperature at 20°C resp. 23°C with standard laboratory conditions (according to EN resp. ASTM) ✓ User-friendly, self-explanatory operation ✓ Quick modification to comply with other standards by a simple exchange of the dropping rod ✓ Predefined test can start after only a few inputs ✓ Easy installation due to compact dimensions ✓ All results and test parameters are stored in an internal database ✓ Accurate, standard compliant positioning of the needle onto the surface of the sample ✓ Automatic cleaning of the needle with drying system for the gypsum cone ✓ High repeatability of the test results ✓ Data transmission to a PC via a serial port (USB type) for extended test evaluation by the optional software VICAT DB
