The Bellstone BHI-CDS-255 Le-Chatelier's Mould is an essential tool for determining the expansion of cement, widely used in construction labs and quality control processes. This mould consists of a spring-tensioned split cylinder with an internal diameter of 30 mm and a height of 30 mm, equipped with two 165 mm indicator stems that allow precise measurements from the cylinder's center. Typically, two to three moulds are required per test, with the procedure carried out in a water bath. By providing accurate expansion readings, this mould ensures cement consistency and stability, making it indispensable for meeting industry standards. Its reliable design makes it perfect for use in high-stakes construction projects, where quality cement performance is critical for safety and durability.
