Performance Characteristics of a Modified Composite Material Containing Inorganic Lightweight Aggregates

Year: 2024

Type: article

Abstract: A modified thermal and sound insulation composite material, potentially applicable in the field of modern construction, has been developed. Experimental samples based on foam glass aggregate (made from recycled waste glass), perlite (with fraction size up to 3 mm) and hydraulic binders were obtained. The acoustic and mechanical characteristics and the thermal conductivity coefficient of the prepared series of composite samples were studied. Values for Rw in the range from 38 to 46 dB and for λ from 0.04 to 0.15 W m-1 K-1 were established. The influence of the different components of the composition on the values of the studied performance indicators and the structure of the composite was analysed.
