Rubber Tamper For Concrete/Mortar Cube Molds - Shore A 80 Hardness, Meets ASTM & AASHTO Standards

About This Product

This is a specialized tool for construction materials testing labs. It's a rubber tamper used to consolidate mortar or grout into cube molds (like 2-inch or 50mm cubes) before they cure. The tamper is made from a specific hard rubber with a Shore A Durometer hardness of 80, which is required by several standard test methods. If you're running tests like ASTM C109 (compressive strength of hydraulic cement mortar) or similar AASHTO standards, you likely need this exact tool to ensure your specimen preparation is up to code. Using the correct tamper helps remove air pockets and create a uniform, consistent test sample, which is crucial for accurate strength results. A simple but essential piece of equipment for any concrete, cement, or mortar testing laboratory.
