Measurement of the thermal properties of different concretes

Abstract

This paper presents experimental work concerning evaluation of the thermal properties of different concretes, with particular reference to their dependence on some other properties of the material such as density, water content, temperature, and type of aggregate. Both mortar and concrete samples have been tested. Measurements of thermal properties have been performed on each sample from a fully saturated to an oven-dry condition. To avoid water migration during the run-time of the thermal tests, a transient measurement method has been used. Two linear parallel probes inserted in the specimen allow the simultaneous measurement of thermal conductivity and thermal diffusivity
