Concrete Cylinder End Grinders are multi-sample preparation units which eliminate the need for qualification testing or documentation of common capping methods. End-grinding is the preferred end-preparation method for concrete samples with design strengths exceeding 7,000psi (48.3mPa).
The Cylinder End Grinder grinds the faces of concrete cylinders plane and parallel to within ASTM C617, usually with just one pass of the diamond wheel. Compression testing can commence immediately after grinding without the use of capping materials. The machine‘s small footprint makes it
