Hardened concrete and mortar
Our concrete laboratory has state-of-the-art technical equipment with which we can undertake all major tests for hardened concrete and hardened mortar in accordance with the European standard EN 12390 as well as other international standards, e.g. RILEM-recommendations, ISO, ASTM and NT BUILD. At customer request concrete compositions can be optimised and special test procedures can be developed.
