Abstract
This paper presents theresults of an experimental program that compares thematerial properties of various types of cementitious composites subjected tohigh temperatures. Within this experimental program, measurements of bulk density, porosity, thermal conductivity, specific heat capacity, permeability and compressive strength of the materials were made. All these properties were measured on test samples exposed tohigh temperatures up to 1000 °C. Theresults of this experimental investigation are thetemperature dependences of the material properties and therelative changes of theproperties at high temperatures in relation totheir values at room temperature. Thepaper also presents and compares different methods for measuring theselected properties studied here, and the effect ofthemeasurement methods on theobtained results. All results are compared with values from thevalid standards and referenced literature.
