| Description | Methods and results of study of selected concrete samples from historical structures are presented and discussed in the paper. The emphasis is put on the right choice of proper field methods of investigation especially on methods of representative sampling of structure together with collection of relevant data about outer and inner environment affecting formation of degradation products (neogenic minerals).They are discussed in detail recommended methods of sample preparation for laboratory study in comparison with own opinions with sample preparation. Both methods of field and laboratory methods have been repeatedly applied and verified in the process of special investigation before remediation of the structure also from the point of view of ratio of amount of relevant results usable for remediation and expended financial resources. The result of study is description of alteration of original composition of building material and detail classification of degradation products both from qualitative and quantitative points of views. An integral part of complex assessment is analysis of formation and progress of degradation processes of building materials caused by interaction of individual material components and in the relation to outer environment. |
