Despite mineral wool waste is only a small fraction of total construction and demolition (CDW) by mass, it requires large transportation landfilling capacities due to its low bulk density, utilization remains compared other CDW types. It essential understand the physical chemical properties this in order utilize it, e.g. as fiber reinforcement composites or supplementary cementitious material. ...

Two fungal species commonly found in indoor environments, Penicillium commune and Paecilomyces variotü, were cultivated on pine wood and on a combination of gypsum board and mineral wool. Air from the cultures was adsorbed on Tenax TA and analysed using thermal desorption-cold trap injection gas chromatography. Identification of the produced volatile metabolites was performed by mass spectromet...

Cements to replace ordinary portland cement (OPC) are currently being studied due the high environmental costs of OPC production. One viable alternative is alkali-activated cements, which can be made from pozzolanic materials such as stone wool fiber waste (SW). At present, SW most used insulation material in world, and disposal recycling it an challenge its fibrous nature low density. In prese...

The purpose of this research is to investigate the acoustic properties natural fibres and compare them with values achieved by common insulation materials used in construction buildings. Three based on biomass were for testing, namely cork, hemp fibreboard. From group conventional materials, mineral wool, propylat polyurethane foam selected. For determining sound absorption coefficient (α), abs...

Global warming potential is one of the most important life cycle assessment indicator, which shows how much heat a greenhouse gas traps in atmosphere relative to CO2. In this study, we calculated global highly insulated building construction detail residential nearly-zero energy based on numerical simulations. To calculate loss constructions, necessary for estimating operational demand use phas...
