Abstract:
This article presents the results of research on the use of unstable steel slag with a fraction of 0/8 mm as a 100% substitute for natural aggregate in concrete production. Two types of cements were used for the production of concrete: Portland cement CEM I 42.5N and hybrid cement H-CEMENT. Both of these cements were produced by the company Považská cementárna, a.s., Ladce. The main objective of this study was to assess the suitable type of binder to be combined with unstable steel slag in the production of concrete composite. The prepared concrete was used to test the properties of a fresh

Abstract:
Most of the problems associated with open cracks in reinforced concrete industrial floors do not arise from technological indiscipline in the execution or exceeding the permitted floor load, but from the geotechnical profile beneath the floor. In the presence of swelling soil in the subsoil, the floors can then be shifted upwards by centimeters and create open cracks. This article describes regression relationships for the prediction of swelling pressure and deformation of reinforced concrete industrial floors based on indirect measurements. These relationships were obtained by evaluating a la

Abstract:
Premature destruction of reinforced concrete structures exposed to aggressive environmental influences is a serious problem, both from a technical and economic point of view. Carbon steel reinforcing bar embedded in concrete is usually not subject to corrosion due to the formation of a protective ion-oxide film that passivates the steel under conditions of strong alkalis in the concrete pores. However, this passivity can be disrupted by chlorides penetrating the concrete, or by carbonation reaching the surface of the reinforcing bar. Then the corrosion begins.An example of a solution to this p

NIH officials worried that the pursuit of narrow, disease-specific goals would funnel resources away from basic science and untargeted research.
