A Cube Mould is a device used in construction for forming concrete test specimens. They are usually made of steel or plastic and come in various sizes, with the most common size being 150 millimeters on each side. The results of cube tests help engineers and contractors ensure that the concrete used in their projects meets the required standards and specifications. Apart from this, the Cube Mould is an essential tool for quality control and quality assurance in construction projects, as it provides valuable information about the strength and durability of concrete mixes.
