the overgrazing and excessive utilization of rangelands has caused vegetationand soil degradation in many rangelands. in the rangeland management, the soil andvegetation elements, environmental factors and livestock should be considered as decisionmaking agents. various methods are applicable for the rangeland restoration as contourfurrows and mortar stone dam. in order to evaluate the effects ...
pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. the injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. the primary purpose o...

Different structural parts of monuments and historic buildings were based on stone as the main building material, such as masonry and foundation, while many types of stones were also used for decorative, architectural elements, such as reliefs, cornices, corbels, colonnettes. The preservation of stone elements is crucial for the continuity of these structures. Mortar on the other hand is an art...
The process of olive oil extraction produces olive stone, a residue which cause considerable problems of disposal. This paper proposes and analyzes an original use of olive stone in order to improve the heat insulation performances of cement lime mortar and reduce its final density. To this purpose, the paper illustrates a set of small-scale tests, which were conducted on specimens of cement li...
On April 25, 2015, a M7.8 earthquake rattled central Nepal; ground motion recorded in Kantipath, Kathmandu, 76.86 km east of the epicenter suggested that the low-frequency component was dominant. We consider data from eight aftershocks following the Gorkha earthquake and analyze ground motion characteristics; we found that most of the ground motion records are dominated by low frequencies for e...
We deal with the textural aspects, porometry and hydric behaviour of combinations of building materials and their durability under attack by salt crystallisation and freezing. We selected 4 types of lime mortar (pure lime mortar, lime mortar + air-entraining agent, lime mortar + pozzolana and lime mortar + air-entraining agent + pozzolana) which were used in combination with either brick or cal...
Since its abandonment 185 years ago, the XII century Santa Maria de Bonaval Monastery located in Guadalajara (Spain) has suffered significant deterioration: first the roof was lost, followed by partial collapse of the walls, moisture infiltration and extensive loss of stone surfaces due to salt weathering. This case study is a clear example of the incompatibility of some building materials: in ...
