An experimental campaign is presented to determine the effects of high temperatures on the mechanical properties of several materials for masonry walls (blocks and mortars), testing a series of cylindrical speci- mens (diameter of 100mm and height of 200mm). After compression tests at 20 °C, an experimental proce- dure was designed for high-temperature testing. The cylindrical samples were heated in a mufﬂe furnace, then were inserted into a speciﬁc apparatus (called ‘thermos’) for maintaining the prescribed temperature, and ﬁnally were subjected to a mechanical compression test. The results obtained by applying this procedure show a common variation of the strength, reduction of modulus of elasticity, and corresponding increments of the ultimate strain with temperature enhancement. Speciﬁc diagrams and discussion on the results are performed for each material. Copyright © 2014 John Wiley & Sons, Ltd.
