PARAMETERS INFLUENCING THE RESULTS WHEN TESTING THE SCALING RESISTANCE OF CONCRETE

摘要

Existing scaling resistance test methods were developed for traditional concrete qualities, but they cannot be expected to always be useful for new concrete types, such as high-performance concrete, etc. In this paper, reflections are made on parameters influencing the scaling resistance test results. These parameters are the freeze/thaw cycle and the pre-conditioning of specimens. The reflections are followed by recommendations on how to perform scaling resistance testing and how to evaluate the results. Where knowledge is lacking, the need for research is identified. The necessity of calibrating test methods against real climatic conditions is discussed as well. Such calibrations are of interest especially where test methods intended to be used for new types of concrete are concerned. Finally, recommendations for standardisation of scaling resistance test methods are given.
