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...

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 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...
