RESISTANCE OF COARSE SEDIMENTS OF THE HUNGARIAN DANUBE SECTION AGAINST CLIMATIC AND ENVIRONMENTAL EFFECTS

Abstract

Complex studies hr!vc lWCll earried out at the Dppartment on th" matnial of gravel fields with different origin by detailed technical-geological evaluation in various parts of the country with the financial support of the Central Geological Office. The demand for the explora- tion. exploitation and utilization of the gravel field in the Hungarian Danube section and its immediate neighbourhood is the main point (with special reference to the choice of gravel supplying regions for individual areas). The durability of stone materiah used for constructions is determined to a great extent by the material quality, characteristic, and unfavourable min- eral components of the rock. The durability characteristics of the pebbly rocks hayc to be known before their use in order to ensure the normal functioning of constructions for a desired period of time. This is the objectiye of the present paper.
