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...
