The two most popular types of end treatment for cylindrical concrete specimens are sulfur mortar capping and neoprene compression pads. Both have their advantages. Neoprene pads are convenient and reusable many times over. Sulfur mortar is economical when testing large numbers of cylinders, and is often the preferred end treatment for cylinders because of its long history of use. Reliable strength results and consistent display of fracture patterns are predictable and well understood. In this article, we go over the equipment and techniques used for sulfur mortar capping.
