Concrete Cylinder Testing Sulfur Capping or Neoprene Pads

Capping of concrete cylinders and drilled concrete cores with sulfur mortar or other capping compounds prepares specimens for compressive strength testing. Specifically this procedure provides plane surfaces perpendicular to the specimen axis to evenly distribute loading forces.

Specimen Preparation Concrete Microscopy Library

The specimens are then cut or ground to expose a fresh surface and that surface is then polished using a series of successively finer grades of diamond paste. This polishing stage is necessary to remove cutting and grinding damage and to expose an unaltered cross section of the material s microstructure.
