“…Many researchers have been carrying out studies about innovative “green” building materials. The difficult disposal of agro-residues has stimulated the interest of the research community in the possible use of agricultural waste products as fibrous matrix of bio-based composites [3]. Furthermore, the wide availability of many “local” natural materials encouraged several researchers to study their sound absorption and thermal insulation properties.…”

In recent years, the interest in reusing recycled fibers as building materials has been growing as a consequence of their ability to reduce the production of waste and the use of virgin resources, taking advantage of the potential that fibrous materials may offer to improve thermal and acoustic comfort. Composite panels, made of 100% wool waste fibers and bound by means of either a chitosan solution and a gum Arabic solution, were tested and characterized in terms of acoustic and non-acoustic properties. Samples with a 5 cm thickness and different density values were made to investigate the influence of flow resistivity on the final performance. Experimental results demonstrated that the samples had thermal conductivity ranging between 0.049 and 0.060 W/(m K), well comparable to conventional building materials. Similarly, acoustic results were very promising, showing absorption coefficients that, for the given thickness, were generally higher than 0.5 from 500 Hz on, and higher than 0.9 from 1 kHz on. Finally, the effects of the non-acoustic properties and of the air gap behind the samples on the acoustic behavior were also analyzed, proving that the agreement with absorption values predicted by empirical models was also very good.

“…Studies of the straw fibers in straw bale have shown two distinct layers of cell structures in straw samples [20,44,47,48]: an outer layer with denser and smaller capillaries and an inner layer with porous and larger capillaries with thinner cell walls. In studies by Vejeliene et al [20] and Bakatovich et al [47], after applying loads on the straw samples, the outer layers of the cells were fragmented, while the inner layer was deformed. When higher load applied, the inner layer of the straw cell was collapsed.…”

The article considers the possibility of using agricultural waste in the development of new building materials in the form of wall blocks. When selecting the compositions, the ideal fractions and ratios of straw to flax were determined, providing the forming of the densest frame of coarse and fine aggregates. Cement and lime were used as a binder. The effect of humidity on the durability and thermal conductivity of straw wall blocks and straw flax boon blocks were investigated. The conditions for the possible occurrence of mold on the block surface of aggregates were studied. According to the results of full-scale tests, the obtained dependencies of the temperature distribution during the coldest period of the winter season were analyzed and the high insulating ability of wall blocks was confirmed. The dependencies of the distribution of humidity over the thickness of the wall blocks after the end of the winter season testing operations were revealed. As a result of the research, a solution for the rational use of plant waste building wall blocks was proposed. The blocks can be applied to the construction of load-bearing and nonload-bearing walls in one-story buildings and multi-story frame construction when filling exterior wall openings.
