| Abstract [eng] |
It is very convenient to evaluate new floating floor constructions by using a small size specimen (1 m2) in real building instead of testing the same construction in a laboratory on a big area (10 m2) specimen (as it is required by the standard). No information has been found in scientific literature about any research in which such small specimens (for example, 0.5 m2) were used. Therefore a question occurred whether such specimens could in fact be used in practice instead of big ones (10 m2) and if so, under what conditions. In order to answer this question, the first step is to study the previous research. It provides the values of small size specimens and how they differ (are smaller) from those of big specimens. As a result of this, a new question has arisen whether the shape (the ratio of the sides of a rectangular specimen) of the specimen does have an influence on the results () or whether only the size of the specimen (area) influences it. In this experiment, the specimen shape was changed from rectangular to square (though maintaining the same specimen’s area of about 0.5 m2). The results of the experiment showed that different shapes of a small specimen have negligible influence on value. Moreover, the experiment results, which provided some answers to previously mentioned questions, led us to offer evaluation methodology for determination and compensation of measurement methodology errors, which are hypothetically independent from physical parameters of floating floor construction components using small area (0.5 m2) specimens. In order to be sure of the correctness of the presented methodology, a reinforcement of further investigation is required. |
