For capping 6" dia. x 12" high (152x305mm) concrete test cylinders when making compression tests. Simplifies capping process by assuring plane end surfaces are right angles to axis of the cylinder. The upright is a guide for positioning the cylinder. Molten capping compound is poured into the mold (plate); then cylinder is placed on the capping material. After the compound is set, the capped is removed for testing. All type of capping compounds can be used with this apparatus.
Capping plate is machined and finish-ground from cold-rolled steel to within .002" (.05mm) planeness. Thinkness of the capping plate is 3/4" (19mm), to allow regrinding and refinishing after considerable usage should the plate become gouged. Capping plates are round, allowing circular rotation during use that results in uniform wearing down of contacting surfaces for maximum length of service. The frame is machined from high-strength aluminum alloy. Meets ASTM C31, C39,C192, C617, AASHTO T22, T23, T126, T231.
