Abstract: The technical textiles are very sensitive materials. To measure the elongation of such a material needs special care. A photographic procedure has been investigated to measure the plain elongation of textile specimens. It is especially suitable for long-term measuring programs. Some experimental results measured by the described method are published.

Abstract: The research topic is the analysis of adobe-clay as a structural material. The behaviour of adobe brick elements of different mixtures were examined. The bricks of various ratios of clay, straw, reed and sawdust were involved in the experiment, in which the process of drying and shrinkage was investigated. Even though only a few data have been obtained so far, some important conclusions were drawn. The first drying period was approximately three weeks long in the laboratory. The tests have shown that organic components like straw, reed and sawdust slow down the drying process. In case of each mixture, a change of weight was observed sooner than shrinkage. The aim of the research is to promote the application of this building material.
