Non-metallic ceramic materials and composites whose softening points are above 1,500 ° C are defined as refractory material.

Refractory materials, which are separated into shaped (e.g. stones, blocks, slabs) and unshaped (e.g. cement, mortar, concrete) materials, are mainly used in high temperature industrial processes.

To determine the requested strength Toni Technik provides intelligent test solutions:

• Determination of compressive strength in accordance with DIN EN 993-5 and DIN EN ISO 8895

• Determination of flexural strength according to DIN EN 993-6, DIN EN 843-1, ASTM C1161, DIN EN 658-3 and DIN EN 843-2

• Determination of modulus of elasticity according to EN 843-2
