Abstract

Pepeo drvne biomase (PDB) nastaje kao otpadni materijal pri proizvodnji energije u energanama na drvnu biomasu. Trenutno se PDB uglavnom odlaže na odlagališta, a budući da su otpadne količine sve veće zbog povećane potrebe za energijom, odlaganje PDB-a predstavlja ekološki problem. Stoga se kroz posljednje desetljeće nastoje pronaći ekološki prihvatljivija rješenja. Iz tog razloga je sve više istraživanja u građevinskoj industriji usmjereno prema iskorištavanju PDB-a kao djelomične zamjene za agregat u cementnim kompozitima. Ovisno o vrsti cementnog kompozita, dodavanje PDB-a kao djelomične zamjene agregata može imati različit utjecaj na različita svojstva. Iako PDB može imati negativan utjecaj na fizikalna i mehanička svojstva cementnih kompozita, pregledom istraživanja vidljivo je da postoji veliki potencijal iskoristivosti PDB-a. Ako bi se mogla dobiti zadovoljavajuća svojstva cementnih kompozita, sačuvao bi se dio prirodnih agregata i smanjio bi se štetan učinak sve većih količina PDB-a na odlagalištima.

Abstract (english)

Wood biomass ash (WBA) is generated as a waste material during energy production in wood biomass power plants. Currently, WBA is mostly disposed of in landfills, and as the waste quantities are increasing due to the growing energy demand, the disposal of WBA poses an environmental problem. Therefore, over the past decade, efforts have been made to find more environmentally friendly solutions. For this reason, there is a growing focus in the construction industry on utilizing WBA as a partial replacement for aggregate in cement composites. Depending on the type of cement composite, adding WBA as a partial aggregate replacement can have varying effects on different properties. Although WBA may have a negative impact on the physical and mechanical properties of cement composites, a review of research shows that there is significant potential for the use of WBA. If properties of cement composites that are meeting specifications could be achieved, it would help preserve natural aggregates and reduce the harmful effects of increasing WBA quantities in landfills.
