THE INFLUENCE OF COMPONENT MATERIALS TYPES AND APLICATION ON THE CHLORIDE ION CONTENT IN SELF-COMPACTING CONCRETE
Considering that one of the most common causes of reinforcement corrosion, and consequently degradation of concrete structures, are chloride ions, it is of utmost importance to know their concentration in concrete. This paper presents the limitations of the chloride ions content in concrete and classes according to European regulations, and the exp...

DIGITAL MODELING OF EARTH'S SURFACE RELIEF
This paper presents the theoretical basis for the development of the Earth's surface relief digital models. The sources and structure of the modeling data, as well as the methods of their processing, are described, depending on the spatial-temporal properties of the Earth's surface. Digital relief models have great significance and wide application...

WATER PERMEABILITY OF ROCK MASS
The presence of water in the rock masses, or water filtering, has an important role in theconstruction of engineering facilities (dams, tunnels, ...), as well as in formation of rockslopes, caused by the implementation of various projects. The rock mass, that we find innature (in-situ), is heterogeneous, anisotropic, jointed and is in the natural s...

THE INFLUENCE OF CONCRETE VISCOUS DEFORMATIONS IN THE CALCULATION OF THE HIGH-RISE BUILDINGS BEHAVIOR OVER TIME
An example of a high-rise building behavior calculation shows that weather deformations of concrete have a significant contribution to changing the behavior of vertical load-bearing elements - columns and walls. The phenomenon of different shrinkage of concrete/steel pillars and concrete core due to the shrinkage and creep of concrete over time is ...

ULTIMATE STRENGTH OF COMPRESSED SLABS AND BOX GIRDERS
A theoretical investigation into the effectiveness of a plate thickness against the ultimate strength of a compressed slabs and box girders is carried out. Series of the buckling analyses, the elastic, the viscoplastic and the ultimate strength are performed by the rheological-dynamical inelastic theory and the finite strip method on a slabs and bo...

ANALYSIS OF LINEAR THERMAL TRANSMITTANCE OF A SIMPLE BALCONY THERMAL BRIDGE
The linear thermal transmittance of a simple balcony thermal bridge with a uniformbalcony slab and wall was analysed. In a five-parameter model (thickness, length andthermal conductivity of a balcony slab; thickness and thermal conductivity of an adjacentwall), it was found that the length of the balcony slab does not influence the thermaltransmitt...

GEOPORTAL FOR SEARCHING AND VISUALIZATION OF CADASTRAL DATA
Geoportal is an indispensable part of the national spatial data infrastructure and a central point of access to spatial data. The paper presents the development of a geoportal based on the principles of service-oriented architecture. Open source frameworks and libraries were used to create geoportal. The aim of the paper is to present a partially d...

MODELING THE RHEOLOGICAL PROPERTIES OF FRESH CONCRETE USING A 3D FINITE ELEMENT MODEL
During the last thirty years, concrete has been industrially mutating from a soft granular medium to a proper non-Newtonian fluid. To benefit from the full potential of the modern fluid concretes such as Self-Compacting Concrete (SCC), prediction tools of the form filling taking into account the properties of the concrete, the shape and size of the...
