ASTM Compression Machines by Matest are four-column prestressed frame systems designed for production routine testing of concrete, fully compliant with ASTM C39, BS 1610, NF P18-411, and AASHTO T22 standards.
These machines feature surface-hardened compression platens, a device to monitor piston excursion during tests, and prestressed columns that ensure exceptional rigidity. The pistons have a 50 mm stroke and are coupled with high-quality packing sets, while the tanks include oil level indicators and discharge systems for precise operation.
A dial speed selector allows users to pre-select and control oil flow, and the multipiston power pump guarantees continuous delivery. The fast approach ram device minimizes dead times, and the ball seating is accurately machined for reliable performance.
Each machine is classified by capacity and load measuring system, providing concrete laboratories with robust, precise, and standardized compression testing solutions.
