• 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 Le Chetelier mould serves for the determination of soundness (volume stability) of cement in accordance with EN 196-3. The mould consists of a flexible sheet body, made of copper-zinc alloy with two indicator needles. Glass plates and additional weights are available as optional accessories.
  • 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 Preparation of prism shaped samples, 40x40x160 mm made of mortar, especially cement mortar in accordance with the standards EN 196 1, ISO 679, DIN EN 12808 4, EN 1015 11 and ASTM C 348. Design and accuracy according to the schedule „Technical Data“.   Advantages ✓ Head ends and separation bars are seperately marked to secure the fitting ✓ A tommy screw enables precise pressure without wedging the parts ✓ The design of the base plate and the surface finishing avoid a deformation of the mould ✓ By use of a brass straight edge the mould guarantees the required dimensional stability long termed ✓ The mould is available alternatively with or without holes for shrinkage tests ✓ Compatible with all components of the ToniLAB ✓ Because of the small weight tolerances the mould is adaptable to instruments of other manufacturers
