Abstract: During freeze-thaw cycles concrete is damaged internally according to the durability of the material. Frost testing of concrete therefore means testing each single concrete com-ponent and their interaction. While the thermodynamic processes are described in the micro-ice-lense-model [1,2] and the internal damage is measured for the whole material a distinction between the durability of single or several components is not yet possible.
In this contribution the aggregates are in the centre of interest which are regarded as mostly inert, solid and durable. The aim of the examination was to make a reliable statement how the results in the CIF-test [3] are influenced by variation of the aggre-gates. Concretes containing several types of aggregates and/or secondary material and a varied preparation are examined by means of relative dynamic modulus measurements. The obtained results reflect clearly different qualities and influences of the aggregates.
