LE CHATELIER MOULD AZA0792

Description

Le Chatelier Mould AZA0792 is a precision instrument used to measure the soundness of hydraulic cement, an essential quality control test that evaluates the volumetric stability of cement after setting. Available through Azalab, this mould ensures accurate results by conforming to international standards such as ASTM C151 and IS 269.

Soundness testing is crucial because it determines the expansion of cement due to excessive free lime or magnesia. Unchecked expansion can lead to cracks and structural failure. The Le Chatelier method uses this mould to measure how much the cement expands during the setting process when exposed to boiling water.

Product Design:

The AZA0792 Le Chatelier Mould consists of:

• A split brass cylinder with two indicator arms
• A base plate made of corrosion-resistant material
• A glass plate or cover for enclosing the test setup

The spring brass construction allows the mould to expand slightly under pressure, while the indicator arms measure the degree of expansion with high precision.

How It Works:

1. A cement paste is poured into the split mould placed on a glass plate.
2. Another glass plate is placed on top to sandwich the mould.
3. The assembly is submerged in water and allowed to set for 24 hours.
4. It is then boiled for 3 hours.
5. After cooling, the distance between the indicator arms is measured.
6. The difference between initial and final distance gives the expansion value.

Applications:

• Testing cement for volumetric stability
• Quality assurance in cement manufacturing
• Research & development in construction materials
• Educational labs in civil engineering courses

Compliance & Standards:

The AZA0792 mould complies with:

• ASTM C151 – Standard Test Method for Autoclave Expansion of Hydraulic Cement
• IS 269 – Indian Standard for Ordinary Portland Cement

Build Quality:

Manufactured from high-grade spring brass, the AZA0792 mould is highly durable, non-corrosive, and easy to clean. The components are precision-machined to ensure repeatability and minimal variation between tests. The indicator arms are calibrated for accurate expansion measurement.

Why Use Le Chatelier Mould?

Cement that expands excessively after setting is considered unsound and can lead to cracking or disintegration of structures. The Le Chatelier test is a non-destructive method that provides reliable data on how cement behaves under extreme conditions.
