For testing the bending tensile strength according to the standards on:
concrete beams / bars
concrete plates
concrete kerb stones
concrete paving stones
natural stone paving stones
Test machine frame with sturdy 4-column construction. The machine columns are chromium-plated. The double-action test cylinder is placed at the top of the machine frame.
The load is measured via an electronic load cell, which is insensitive to lateral force, mounted at the top in the direct line of force.
