Neka svojstva peno-betona

Abstract

U svetskoj praksi primena peno - betona je veoma raširena, naročito za prekrivanje i termičku izolaciju industrijskih i komercijalnih zgrada. Ovim projektom hteli smo da približimo građevinskoj javnosti mogućnosti primene određenih materijala, njihovih svojstava, tehnike dobijanja peno - betona i adekvatne načine ugradnje. Naznačena su glavna svojstva peno - betona (zapreminska masa u suvom stanju, zapreminska masa u svežem stanju, pritisna čvrstoća, modul elastičnosti, skupljanje usled sušenja, termička ekspanzija termička provodljivost..). Takođe, ovde se daju mogućnosti primene peno betona u određenim delovima konstrukcije. Važno je napomenuti da je proizvodnja peno - betona u Evropi u ekspanziji, dok se peno - beton u Americi i Indoneziji koristi u značajnoj meri. Na osnovu toga jasno je da su i rezultati istraživanja na ovom polju u Americi na daleko višem nivou nego u Evropi.

Foam-concrete has worldwide application, especially in covering and thermal isolation of industrial and commercial buildings. Our intention with this project was to clearly represent the possibilities of application of certain materials, their properties, production techniques and modalities of application, to engineering society. Main properties of foam-concrete were listed (such as: bulk density in dry density, bulk density of green concrete compressive strength, modulus of elasticity, thermal movement, thermal conductivity..). This project also is listing possibilities of foam-concrete application in different parts of building. It is important to emphasize that the production of foam concrete in Europe is in its expansion while the foam-concrete in USA and Indonesia is being widely used. Based on that, it is clear that the conclusion can be drawn that the research results in this field in USA are at a much higher level than in Europe.
