This work evaluates the performance of cement-based composites made with rice husk and intended to be used in acoustic barriers and as thermal insulating material in a multilayer system. Because acoustic barriers are exposed to external conditions and mechanical loads, a wide range of laboratory tests were performed to evaluate the mechanical, dura...

This research concerns the study of composite boards made from polymer-based materials that include rice husk and recycled rubber granules, to see if they can mitigate vibrations and improve the impact sound insulation of floor solutions in buildings. The influence of the composite mix, mass density and board thickness on the overall performance wa...

In the construction sector, the development of innovative material has been adopting sustainability strategies to reduce the negative impacts of this industry. One of the most relevant strategy over the last years has been the incorporation of waste on building materials. In this context, used rubber and rice husk are both waste materials generated...

In this work, innovative polymer-based composite materials made with rice husk and expanded cork byproducts have been produced and characterised. First, rice husks and expanded cork granules were studied separately to ascertain material properties, such as thermal conductivity, water vapour resistance, thermal stability and specific heat capacity....

This study assesses the performance of sustainable building walls made from 80 kg/m3 and 100 kg/m3 straw bales. Experimental tests based on the procedures set out in conventional testing guidelines were designed to evaluate their hygrothermal and acoustic characteristics. First, experimental tests were performed to characterise intrinsic properties...

The construction sector has been adopting sustainability strategies to reduce the negative impacts of this industry. One of the most relevant strategies over the last years has been the incorporation of waste and natural materials. There has also been a more systematic demand for high-performance products with improved technical properties. Due to...

The concept of sustainability applied to the construction sector has stimulated the development of unconventional building materials using waste and renewable resources. The application of by-products from the agro-industry, such as rice straw and husk, has been studied and successfully used as building insulation materials due to their insulation...

The construction sector has a significant social and economic impact on the European Union (EU), contributing towards employment opportunities (over 20 million directly dependent jobs). However, it is important to take into account the negative impacts of this industry, especially regarding the environment. As an important resources consumer, the c...

Within a full-scope modernization programme of Portuguese secondary schools, technical inspections were conducted in order (i) to identify the main degradation processes that affect different types of school buildings and (ii) to provide recommendations for the rehabilitation projects. This paper presents the constructive characteristics and a stat...
