Abstract

The article evaluates a moistened office building built before 1950 after the interval of three years, where a non-destructive moisture rehabilitation was performed using the developed hydrophilic plasters. The evaluation is carried out by means of Delphin software allowing you to take into account the moistening effects taking place in the construction over time and providing exact outputs in the form of specific values describing the moisture content achieved in the masonry. The simulation is based on the measured moisture parameters obtained during the three years of building monitoring, mutually comparing the so-called soft plaster rehabilitation methods according to the WTA with plasters based on polyurethane fillers and plasters based on aluminosilicate waste created during the production of cellular concrete.

Abstract

Prilog opisuje uporabu poliuretanske pjene nakon završetka njezinog životnog ciklusa kao agregata i za toplinske izolacije žbuke za različite zidne površine i za laki beton. Ovdje su opisane struktura i fizikalno-mehanička svojstva toplinske izolacijske žbuke. Nadalje se daje provjera primjene toplinske izolacijske poliuretanske žbuke u debljini 50 do 70 mm na referentnoj zgradi, kod koje su vanjski zidovi izolirani. Drugo važno područje kojim se bavi ovaj prilog je da se poliuretanska pjena veličine zrna od 0,125 do 6 mm koristi kao agregat kod lakog betona. Prikazana su fizikalna i mehanička svojstava betona od poliuretana različitih gustoća i primjer njegove prerade., The contribution describes the use of polyurethane foam after the end of its life cycle as an aggregate both for thermal insulating mortars for various wall surfaces and for lightweight concrete. The structure and the physical and mechanical properties of thermal insulating mortar are described here. The verification of application of thermal insulating polyurethane mortar in the thickness of 50 ÷ 70 mm to a reference building, where external walls were insulated, is provided further. The second important area dealt with in this contribution is that of lightweight concrete, for which polyurethane foam of grain size of 0,125 ÷ 6 mm is used as an aggregate. The physical and mechanical properties of polyurethane concrete of various densities and an example of its prefabrication are presented.
