About LE Chatelier Mould

LE Chatelier Mould MTCT-13

Cement of good quality does not contain the impurities like free lime, magnesia and sulphates, so this should be checked before use. When it contains the impurities named above, it can expand after reacted with the water, which will result in the unwanted results like, cracking, unwanted expansion of the dimensions and lower strength. Prepare a cement paste of 78% of standard consistency of the cement, and fill it into the split brass cylinder. Cover the top and bottom of the cylinder and put it in water at 27 degrees Celsius for 24 hours. After 24 hours, measure the separation between the two indicators at their pointed ends. Then heat the whole water and immersed cylinder with paste up to a boiling temperature in 30-35 minutes and then boiling for 3 hours. After cooling it down, again measure the separation between the two pointers.

Technical Specification

Temperature 27 2 C
Humidity 65 5 %
Volume expansion in cement mortar or in cement concrete is caused by the presence of UN burnt lime (CaO), dead burnt MgO and also CaSO4.
By Le-chatelier method we can only find out presence of un burnt lime (CaO).
Presence of UN burnt lime may develop cracks in the cement because of increase in volume.
Free lime (CaO) and magnesia (MgO) are known to react with water very slowly and increase in volume considerably, which result in cracking, distortion and disintegration
Two parallel demonstrating arms with pointed closures are connected.

Precise Cement Soundness Testing

The LE Chatelier Mould is crafted from polished brass, offering high accuracy for measuring cement expansion. Supplied with a glass plate and two weights, it enables consistent and repeatable results, critical for cement quality assessment in construction projects. Its manual operation and instant response time make it an essential tool for laboratory technicians.

Built to International Standards

Adhering to IS 4031 specifications, the LE Chatelier Mould guarantees reliability and compliance with industry benchmarks. The moulds dimensions and supplied accessories ensure tests can be performed efficiently and accurately, supporting both research institutions and commercial laboratories in India and beyond.

Simple and Safe Laboratory Operation

With manual control and a bench-top mounting design, the LE Chatelier Mould is both user-friendly and safe. The robust brass construction ensures durability, while precise indicating arms and instant readings enhance usability, making it suitable for regular testing routines.

FAQs of LE Chatelier Mould:

Q: How is the LE Chatelier Mould used in cement testing procedures?

A: The LE Chatelier Mould is used to evaluate the soundness of cement by measuring its expansion when subjected to specific conditions. The cement paste is placed in the brass mould, covered with the supplied glass plate, and held with the weights. After curing at the specified temperature and humidity, measurements are taken manually using the indicating arms.

Q: What is the benefit of using a brass construction for the mould?

A: The brass construction ensures robust durability, corrosion resistance, and stable dimensional accuracy, which maintains consistent results over repeated usage and enhances the reliability of cement testing.

Q: When should the LE Chatelier Mould be employed in a construction project?

A: This equipment is essential whenever cement soundness needs to be assessed, typically during the quality control phase, prior to using cement in structural work. This prevents future expansion issues that could compromise structural integrity.

Q: Where is the LE Chatelier Mould best suited for installation and operation?

A: The mould is designed for bench-top use in laboratory settings, such as construction material testing labs, research facilities, or quality control departments in cement manufacturing plants.

Q: What is the process for preparing a specimen in the LE Chatelier Mould?

A: A cement paste specimen is mixed according to standard procedures and placed into the internal cavity of the brass split mould. The glass plate and weights are positioned as supplied. The specimen is then subjected to controlled temperature and humidity before measurements are manually recorded.

Q: How accurate are the measurements with this mould?

A: The LE Chatelier Mould delivers accurate measurements as per IS 4031 requirements, with instantaneous response on manual measurement, making it reliable for detecting minute expansions in cement specimens.
