ABSTRACT

The paper summarizes the results of assessment of geo mechanical characteristics of
rock samples collected from the Sibiu County: Valea Strâmbului-Rasinari and Valea
Marajdia. The rock characteristics are influenced by climate factors, in particular
temperature and humidity. When the phenomenon of frost occurs, rock stretches and
some strains are acting that lead to a deterioration of the structure and internal stability,
thereby reducing the characteristics of resistance and strength.

Within this scope, several types of rock were taken into account, for which the required
geo mechanical characteristics in construction use were assessed.

In this respect, the paper deals with the physical, mechanical, elastic tubes and technology on the rocks dry, saturated, and subjected to 25-50 cycles of freeze-thaw.

Coefficients were determined by soaking, gelivity and values obtained were compared
with those required by standards. Results of laboratory experiments on rock samples
were analyzed in terms of framing the rules stipulated in standards for possible used like
construction materials.

Keywords: geomechanic characteristics, experimental tests, rocks, constructions materials
