ABSTRACT
ABSTRACT: RC elements in case of underground and network infrastructure, are subjected to the activity of different agents, i.e. water, chemicals and oil-products. Because of it so important is their durability. Indispensable are then suitable repairs, because the possibility of the underground exchange of elements is comparatively difficult and expensive. In the relationship with the environment which can appear in objects of the infrastructure, repair methods must be resistant to the activity of different environments, and must also be prepared to the repair of concrete surfaces with the different state: moisture and oiling. Comparing the influence of various oil products on compressive strength of concrete, leads to the conclusion that there are large differences in effects. The repair of oiled structures is technologically difficult. The paper will present research works on some nano-and modern technologies in case of oiled RC structures.
