EVALUATION OF PROPERTIES OF MASONRY MORTARS BLENDED WITH CERAMIC WASTE POWDER
Aiming to meet the principals of the modern circular economy, this study explores the possibility of using locally available waste materials in the production of innovative, eco-friendly mortar for masonry. The eco-binder, applied as a substitute for cementitious material, is ceramic waste powder (CWP) generated during the production of ceramic ind...

EFFECT OF THE HRWRA QUANTITY ON DURABILITY PROPERTIES OF SELF-COMPACTING CONCRETE
The paper presents the results of our own experimental research on the effect of the high range water reducing admixture content – HRWRA (applied in the range from 0.8 to 1.2% by mass of cement – mc) on the properties of self-compacting concrete in the fresh and hardened state. The research showed that increasing the HRWRA content lead...

DYNAMIC AMPLIFICATION FACTOR OF ROAD BRIDGES – ANALYTICAL AND EXPERIMENTAL FINDINGS
This paper discusses the problem of theoretical and experimental determination of dynamic factors of road bridges. Various parameters influencing the dynamic behavior of bridges are briefly described and a review of regulations in this field is given. Also, an example of the numerical determination of the dynamic amplification factor on a specific ...

THE INFLUENCE OF CONCRETE VISCOUS DEFORMATIONS DURING BEHAVIOR CALCULATION OF CABLE-STAYED BRIDGES
On the calculation example of a cable-stayed bridge with oblique cables, it was pointed out the shrinkage and creep of concrete significantly affects the distribution of stresses and deflections of the span beam over time. The segmental type of bridge construction is considered, which implies the successive introduction of concrete rheology, for ca...

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 ...
