Treść
Compressive strength is commonly used for characterising the properties of refractory materials. There are a number of standards which specify the methodology applied for testing dense shaped materials, insulating materials and unshaped materials. They contain requirements regarding the shape and size, the dimensional tolerance of test pieces, the manner of their preparation, the load rate and preload applied, the hardness and roughness of loading plates as well as the use of packing. These requirements are not fully defined in all the standards. Moreover, there are factors not defined in standards which can influence the obtained results of cold crushing strength (CCS). The article presents investigations conducted within the framework of ReStaR project, aimed at determining the influence of factors related to the CCS determination procedure on the result. In order to identify factors having the greatest influence on CCS determination in the case of dense formed, insulating and unshaped materials, the factorial design and variance analysis has been applied. For each of these materials, each of the influencing factors on two adopted levels was examined. It was found that a considerable impact on the determination result was exerted by the quality of preparing the test pieces, their format, in particular the application of preload and load rate in the case of unshaped products. It should be noted that the influence of the last one is different for dense products and insulating ones. The application of packing exerts a strong effect on a decrease of CCS value. In case of dense and insulating materials for factors chosen after preliminary tests it was found that there is no important factors on the tested levels if the amount of tests is large enough. In case of unshaped material preparation and format of test pieces plays a key role for CCS results.
