The Volume Change Apparatus is used to measure the linear expansion or contraction of cement mortar or concrete during the setting and hardening process. It helps determine the soundness and dimensional stability of cement, essential for high-quality construction. The apparatus typically consists of a Le Chatelier mold made of brass with two indicators, a graduated scale, and glass plates for accurate readings. This test evaluates the expansion caused by excess lime or magnesia in cement, helping maintain structural integrity. Built from durable materials and precision-engineered components, the apparatus ensures accurate and repeatable results in both laboratory and field testing environments.
