“…Going in the greenest direction manufacturing, a product should be constituted from natural components as well as be recyclable. In this context gypsum reinforced by hemp fibers appears to be a valid material, indeed its constituents derived from natural original and the gypsum matrix leads itself well to be recycled: the dihydrate and hemihydrates phases of calcium sulfate can be converted into each other under certain conditions, which provides a basic theory for the recycling of waste gypsum [2,5].…”

“…After tests, the hemp fabrics were extracted, and the pieces of gypsum were recovered and subjected to grinding by using a commercial blender with a grinding velocity of 30000 rpm and a time of 3 minutes. These parameters were chosen according to what established in authors' previous research work [2].…”

“…Also these parameters were chosen according to what established in authors' previous research work [2]. Therefore, thermogravimetric analyses (TG, Netzsch, model 409ST Luxx) were carried out in order to confirm that the heat treatment conditions allow to convert the dihydrate phase into the hemihydrates phases of calcium sulfate.…”

“…Gypsum is one of the earliest building materials and its application history can be traced back to 4000 years ago [1][2][3]. Its easy fabrication, low energy consumption and price, good aesthetic appearance, good fire resistance, good recyclability, good sound and thermal isolation properties, make gypsum one of the most important construction materials used in house building applications and often it is preferable to other building materials (wood, plywood, etc.)…”

Gypsum is an ancient material, still widely used and suitable for many applications in the constructions due to its low cost, availability, lightweight, good thermal and sound isolating behaviour, fire resistance and low energy consumption. One of the most established application is its use as building walls and as pointed out in authors previous research works, it can be very useful and interesting to reinforce the gypsum with vegetable fibres like hemp. This aspect is in line with the current world situation where every industrial company needs to decrease the materials waste, increase recyclability and use more eco-friendly materials. Therefore, this work aims at designing, manufacturing, and testing of both commercial and recycled gypsum specimens reinforced with hemp fabrics, in order to improve impact and flexural resistance of traditional gypsum boards. The recycling process was carefully studied to detect the best grinding time, temperature and time of the heat treatment required to allow the reutilization of gypsum powders. Three point bending and impact tests at different energy levels were carried out in order to understand how the presence of the hemp fabrics within the gypsum matrix and how the recycling process affect the mechanical response of reinforced gypsum.

“…In this regard, the incorporation of phase change materials (PCMs) in conventional building materials (Alzoubi et al, 2020) such as gypsum has been studied because it is a commonly used material in construction due to its low energy cost of production (Lushnikova & Dvorkin, 2016) and its fire resistance (Castellón et al, 2021) and acoustic insulation (Boccarusso et al, 2020) properties.…”

This investigation studied the heat storage capacity of a gypsum blinder with a hybrid nanocomposite (NH) of vanadium dioxide and multiwall carbon nanotubes (VO2/MWCNT). The influence of the NH in the hydration kinetics and hydrated products was determined. The effect of the incorporated amount of NH in the wettability, mass loss by humectation-drying cycles, thermal conductivity, specific heat (Cp) and gypsum thermal performance at 40 °C was determined. Characterization techniques exhibited that the presence of VO2/MWCNT did not modify hydration kinetics and phases development, water drop angle or compressive strength. Nevertheless, gypsum blinders mass loss increased with the presence of the nanocomposite after 6 humectation-drying cycles. According to the thermal properties, it was found that the NH addition increased gypsum blinders thermal conductivity and Cp values. Finally, it was concluded that gypsum with VO2/MWCNT promotes self-thermal regulation properties without affecting its performance. The usage of VO2/MWCNT embedded in a gypsum as a construction material would provide thermal comfort conditions in buildings.
