Abstract:
In addition to the basic composition of the earth, which varies depending on the location of the excavation, the traditional experience tells about different supplements which are used to repair characteristics during the construction. Additives can be organic or of organic origin (lime, sand, animal blood, cow faeces) as a repairs of basic mixture, then the different fibers in the form of micro armature (hair, chaff, chopped straw, algae, needles of evergreen plants and etc.) different stalks of plants as micro armature (cane, hemp, tree branches). Laboratory testing conducted in this case shows the possibilities of use of pine needles as armature in addition to fir needles, which improves the mechanical characteristics of the earth. It is clear that the improvements made with natural materials directly affect the cost-effectiveness of this type of construction.

Key words:
earth, mixture, fir and pine needles, characteristics.
