Durability and repair of building structures
(Preface) :
Due to the different durability of building structures, the 21st century has become a
century of repair work and rehabilitation for construction. Along with the decreasing
amount of area zoned for construction, the increase of such activities in inevitable. The
world economic crisis continues to hold back new investments and, therefore, also
contributes to this situation. Naturally aging building complexes and, unfortunately, more
and more frequently new buildings as well, contain design or construction errors. It is
best if the mistakes are noticed during the completion of objects, worse if they don't
become noticeable until they are under exploitation. The detrimental effect of the natural
environment and negative influence of people cannot be ignored. Due to the increasing
aggressiveness of environments and natural aging processes of building structures, the
necessity to repair and protect them is becoming increasingly common. The beginning of the
21st century is a period of noticeable climate changes, as well as a time of growing
global awareness of dangers which, in turn, has led to the dynamic development of building
materials and new technologies. Nanotechnologies and related products, which formerly
found application only in cosmetology or medicine, have begun to play a role in
construction. As a result of this, construction chemistry has gained importance and
proceeded to strengthen the link between construction and classic chemistry. Taking into
account both the dangers and challenges that the 21st century poses, such as global
warming, reduction of energy consumptions, and restrictions regarding CO2 emissions to the
atmosphere, this field of studies will play a key role in the construction industry in the
future. Conducting the repair work on a given object or its fragment, entails an
individual approach, depending on the type of object, the accepted structural solution,
its size and function. Such currently widespread repairs have become a broad
civilizational issue and are encountered in all kinds of constructions. This is why the
durability and effectiveness of such repairs has become of utmost importance.
