Evaluating geomorphologic conditions in the areas of gullies spreading represents an important step in the capitalization of land and spatial planning. The research was carried out in the Apold Depression (Southern Transylvania, Romania), a submontainous area of approximately 280 km2 characterized by homogeneous physical-geographical and anthropogenic conditions. Gullies (ravines) have been identified on an area of 33 km2 (11.79% of the depression). Morphometric assessment of the conditions of gullies spreading wa...

The article presents the material, both on theoretical and practical issues of rational use of agricultural land in the North Caucasus Federal District (NCFD), as well as an analysis of the main reasons that led to their degradation. Assess ongoing processes on agricultural lands with their heavy use. An important feature of the NCFD district is the high proportion of rural population (49.7%) is the highest in the Russian Federation. Revealed major shortcomings in the organization and use of land resources, which ...

The foundry sand wastes (FSW) are likely to constitute as raw material for the manufacture of cement mortars or concretes at a low cost. For this reason, present work has main objective to use the foundry sand wastes in self-compacting mortar as a fine aggregate (by a partial sand substitution). An experimental tests were carried out to evaluate fresh (slump test) and hardened (bulk density, compressive and flexural strength and elastic modulus) properties of SCMs based on FSW. The Natural Sand (NS) is substituted...

This study aims to valorise the mineral wastes in particular glass wastes, brick wastes and clay to produce granulated foam glass at different characteristics (G1: Granulate foam glass without additive; G2: Granulate foam glass with 10% clay and Granulate foam glass with 10% Brick wastes). The aggregates of foam glass were manufactured at a temperature 850 ° C from glass wastes (cullet), brick wastes, clay and limestone as a foaming agent. Mixtures of Self-compacting mortar have been developed with elaborated foam...
