Characterization of an Arundo donax-based composite: A solution to improve indo...
Cintura, Eleonora; Faria, Paulina; Molari, Luisa; Barbaresi, Luca; D'ORAZIO, DARIO; Nunes, LinaABSTRACT: Arundo donax (giant reed or giant cane) is a widely available, perennial, invasive, non-food crop, present worldwide and employed for several uses, including building practices. Considering the increasing demand for sustainable building materials, A. donax can be an efficient solution. This study investigated its properties as a bio-aggregate mixed with a sodium silicate solution as an adhesive. A hor...
Development of bio-based particleboards for buildings' indoor use
Cintura, EleonoraThe environmental problems are more and more serious, and solutions to moderate climate change are urgently required. The construction sector is widely responsible for energy, water, and raw materials consumption and for pollution; thus, the use of low embodied energy and sustainable building products are efficient possibilities to overcome environmental challenges. Nowadays the opportunity of enhancing and re-...
Bio-based boards made of hazelnut shell and A. donax for indoor applications - ...
Cintura, Eleonora; Faria, Paulina; Molari, Luisa; Mazzocchetti, Laura; Dalle Donne, Matteo; Giorgini, Loris; Nunes, LinaThe present study investigated the reaction to fire of bio-based boards for indoor applications made of A. donax and hazelnut shells as aggregates. A sodium silicate solution was employed as the adhesive due to its several advantages. Among others, the possibility of moderating some of the main drawbacks of bio-based building composites, such as the resistance to fire. The considered materials were analysed bot...
Hygroscopicity and Morphology of Bio-Based Boards—The Influence of the Formulation
Cintura, Eleonora; Nunes, Lina; Molari, Luisa; Bettuzzi, Matteo; Morigi, Maria Pia; Brancaccio, Rosa; Faria, PaulinaThe internal structures and the hygroscopicity of bio-based boards consisting of giant reed (Arundo donax L.) and hazelnut shells as bio-aggregates, and a sodium silicate solution as the adhesive, were investigated. The aim was to evaluate the influence of each material (the bio-aggregates and adhesive) and their distributions in the boards on the final performance. By carrying out X-ray computed tomography, th...
A feasible re-use of an agro-industrial by-product: Hazelnut shells as high-mas...
Cintura, Eleonora; Faria, Paulina; Molari, Luisa; Barbaresi, Luca; D'Orazio, Dario; Nunes, LinaThe present work investigates the feasibility of producing boards, with unconventional materials, namely hazelnut shells as a high-mass bio-aggregate and a sodium silicate solution as a no-toxic adhesive, and discusses possible applications based on an extensive characterization. The aim is to define a feasible reuse of a largely produced agro-industrial by-product to reduce the high environmental impact caused...
Eco-efficient boards with agro-industrial wastes – Assessment of different adhe...
Cintura, Eleonora; Faria, Paulina; Duarte, Marta; Nunes, LinaLaboratory tests were carried out to evaluate the feasibility of producing boards or coating panels with good hygrothermal performance by using different agro-industrial wastes (grape and olive press wastes, hazelnut shells, spent coffee and pine) and adhesives (gypsum-based binder, sodium silicate solution and starch-based glue). Hygrothermal properties and resistance to mould growth, including the effect of c...
Bio-Wastes as Aggregates for Eco-Efficient Boards and Panels: Screening Tests o...
Cintura, Eleonora; Faria, Paulina; Duarte, Marta; Nunes, LinaScreening tests were developed or adapted from RILEM recommendations, standards and past studies, and carried out to characterize some agro-industrial wastes and to assess their feasibility as aggregates for eco-efficient building composites. Spent coffee grounds, grape and olive press waste and hazelnut shells were used, as well as maritime pine chips as control material. Particle size distribution, loose bulk...
Cement-Bonded Particleboards with Banana Pseudostem Waste : Physical Performanc...
Nunes, Lina; Cintura, Eleonora; Parracha, João Luís; Fernandes, Bruno; Silva, Vitor; Faria, PaulinaThis article evaluates the relevant properties of cement-bonded particleboards (CBPB) made with a portion of maritime pine (Pinus pinaster) particles replaced with an agricultural waste, banana pseudostem (Musa sp.). The industrial production of CBPB was simulated in the laboratory based on a reference composition defined by a manufacturing company. Test specimens were produced assuming 0%, 25%, 50% and 75% par...
Agro-industrial wastes as building insulation materials: A review and challenge...
Cintura, Eleonora; Nunes, Lina; Esteves, Bruno; Faria, PaulinaThis study investigates the possibility of using agro-industrial wastes for building products, mainly focusing on their insulation properties. A classification of bio-wastes is provided, namely of the lignocellulosic ones and their features and properties are described. Information about three main topics is collected: world production and consumption of some crops already used as building materials, their chem...
