Compression Testing Machines

Compact Cement & Mortar Testing System Series DB

Dual-station hydraulic testing machine for compression (300 kN) and flexural bending (20 kN) testing of cement and mortar prisms per EN 196-1 and ASTM C109.

Part No: DB-300/20
EN 196-1 EN ISO 7500-1 Class 0.5 ASTM C109 / C109M ASTM C348 DIN EN 1015-11

Overview

The TestingGmbH Series DB is an integrated dual-station testing machine specifically designed for testing cement, mortar, grouts, and binders. The right test space features a rigid 300 kN compression frame for 40 x 40 mm prism halves and mortar cubes, while the left test space contains a 20 kN flexural fixture for standard 40 x 40 x 160 mm prisms. Equipped with separate differential area servohydraulic cylinders and high-precision load cells, it delivers Class 0.5 measuring accuracy according to EN 196-1, EN ISO 7500-1, ASTM C109, and ASTM C348.

Applications

Compressive strength of cement and mortar prisms (40 x 40 mm)
Flexural strength of standard cement prisms (40 x 40 x 160 mm)
Testing of gypsum, anhydrite, screed, and lime mortars
High-early-strength binder development and quality verification
Research on cementitious composites and chemical admixtures
