Capping is required to give a smooth surface for applying compressive load to concrete cylinders. Only cylindrical concrete test specimens are capped using appropriate method. When the ends of cylindrical test specimens are not plane within 0.05 mm, it is required to cap those test specimens. The capped surfaces should be at right angles to the axis of the specimens. After capping the specimen, check the plainness of cap by means of a straight edge and feeler gauge, making a minimum of three measurements on different diameters. Caps are made as thin as practicable and it should not get damaged when the specimen is tested.
Why do we use sulfur compound in capping cylindrical concrete specimen?
Capping concrete cylinders and grout prisms with sulfur mortar helps to give them a plane, level surface, so that force is applied evenly to the entire end surface when the specimen is broken during the ASTM C39 procedure to test compressive strength.
What is a Sulphur capping set?
The Sulfur capping compound features ultra-strong hot-blended flakes for guaranteed consistency from sulfur, mineral filler, and special components. This provides top performance, even for high-strength concrete tests. The sulfur capping compound melts quickly at 240° - 260°F (116° - 127°C).
