Testing of building materials - reaction to fire
(Proceedings of the 17th Conference with International participation risk and safety engineering, Kopaonik, 2022)
To reduce occurrence of fires in buildings as efficiently as possible, it is necessary to take into account active and passive fire protection measures during construction of building. This paper will show more about passive ...
The role of drainage systems in the prevention of material degradation of bridge structures
(XXIII YuCorr, Divčibare, Serbia, 2022)
The paper gives an illustrative presentation of damage to the material of bridge structures
due to failure to maintain the system for drainage of bridges. Damage is caused by mechanical
erosion and abrasion or by chemical ...
European and national assessment procedure for the fire performance of facades
