“…Specifically, they reported that cork, as the outer bark layer, consists of 30% to 50% of suberin and because of the thermal insulation properties that it possesses, suberin makes bark a very promising alternative building and insulation material compared with the conventional ones (among other unique properties such as, insulating properties, hydrophobicity, visco‐elasticity, versatility, etc.). Orhon and Altin 33 also reported that bark is composed mainly of cellulose and suberin. Their study presents cork as a lightweight, flexible, fire‐resistant, biodegradable material with low conductivity of heat, sound, and vibration, thus characterizing bark as an excellent option for thermal and acoustic bio‐insulation.…”

This review gives an overview of recent advances in research on the role of tree bark material in bark-cement bio-composites, and their potential as building insulation materials. Suberin and other bark extractives seem to be of great importance for the insulation properties of such composites. Bark is a readily available, biological raw material with unique properties and it has revealed promising results as a bio-insulation material, either alone or in mixtures with different matrices (cement, lime, resins, polymers, etc.). The thermal, mechanical, acoustic, and hygroscopic properties of these bark-insulating composites depend on several factors, primarily the type of tree bark, the density and mechanical strength of the bark, the density of the boards produced, and the ratio of bark material to the binder material used in the board production (cement, lime, resins, polymers, etc.). The size of granules and the thickness of the board produced seem to be factors with a lower impact on the properties of the bark-cement composites. A low proportion of bark fibers or particles (0.5-1%) in bark-cement composites has proven highly beneficial to their mechanical and thermal properties and ensures higher workability of the mixture. Different modification treatments of bark material should be investigated, with the aim of decreasing the bark extractives content, to improving the cement setting, decreasing the unstable hemicellulose components and their hygroscopic nature, improving the bark particles' durability in alkaline environments, and upgrading their adherence properties. As the demand for alternative, sustainable structural materials keeps rising, the cement-bark composites will undoubtedly keep attracting the attention of the scientific and industrial world.

“…is reported to be associated with the use of a considerable amount of energy, depletion of natural resources, release of noxious pollutants into the land, air, water, among other things (Orhon and Altin, 2019). It is also reported that rapid urbanisation and overpopulation contribute to environmental problems due to the non-sustainable ways of exploiting conventional building materials (Orhon and Altin, 2019). Among other related issues, these problems have called for the need to exploit alternative building materials for use in the construction industry.…”

“…Alternative building materials refer to materials or a combination of materials that use available natural resources instead of conventional non-green resources to reduce the inefficient consumption of energy and supplies to help achieve sustainability in buildings (Omer and Noguchi, 2020). Most alternative building materials are composed of raw materials obtained from rapidly renewable resources (products made from agricultural products typically harvested in ten years or less) like bamboo, hemp, straw, rice husk and others (Orhon and Altin, 2019). According to Krueger et al (2019), green building guides talk about several diversities of alternative building materials, which can replace conventional materials.…”

PurposeThe increased awareness of global environmental threats like climate change has created an upsurge of interest in low embodied carbon building materials for green building delivery. Though the literature advocates for the use of hemp-based building materials, there is no evidence of studies to explore its potential use in Ghana. Therefore, this study explores the potential factors that limit the adoption of hemp as an alternative sustainable material for green building delivery in Ghana.Design/methodology/approachA structured questionnaire was used to solicit the views of built environment professionals operating in construction, consulting and developer firms. The questions were developed through a comparative review of the related literature and complemented with a pilot review. Data were analysed via descriptive and inferential statistics.FindingsOn the average, the majority of the respondents showed a moderate level of awareness of hemp and its related uses in the construction industry. Also, certain key factors like the perceived association of hemp with marijuana, lack of expertise in the production of hemp-related building materials, farmers not getting the needed clearance for the cultivation of hemp, lack of legislation by the government in the legalisation of hemp and the inadequate knowledge of consumers on the benefits of hemp-based building materials were identified as potential limitations to the adoption of hemp as an alternative sustainable material for green building delivery.Originality/valueThe findings from this study provide insights into a less investigated area in sub-Saharan Africa and further provide new and additional information to the current state-of-the-art on the potential for the use of hemp in the building construction sector.

“…Prefabricated and modular houses typically require laminate panels for their construction. This study aims to investigate the feasibility of using slate reinforced with cork as an alternative building material for sustainable construction, particularly in the manufacture of laminate panels for facades or interior use in prefabricated and modular houses [56]. The production process involves thoroughly bonding the components-an elastic adhesive, slate, and cork-together to create the panels.…”

This study investigates the feasibility of using a composite material comprising slate reinforced with cork sheets for architectural purposes like facades and wall coverings. The research involves the comprehensive characterisation of both slate and cork materials along with the evaluation of the silicone adhesive used in their bonding process, specifically Sikasil® HT from SIKA®. It was found that both slate and cork exhibited low wettability, which was enhanced through cold plasma treatment. Subsequently, a composite sandwich structure was fabricated and subjected to impact testing in a drop tower, along with fire resistance evaluations. The fire tests revealed that when subjected to a flame of 900 °C for 15 min, the slate alone heated rapidly, reaching 500 °C within 3 min on the side opposite to the flame. However, the sandwich structure reached 260 °C on the cork side (opposite to the flame) at 7.5 min, maintaining this temperature until the deterioration or detachment of the cork between 11 and 12 min. This provided insulation and delayed ignition. The sandwich structure maintained its fire resistance due to the insulating properties of cork and the superior thermal resistance of silicone compared to other adhesives up to 260 °C. Overall, the results suggest the potential suitability of this sandwich structure for architectural applications. Its favourable adhesion properties and acceptable fire resistance indicate that it could serve as a viable alternative for construction materials in architectural contexts.
