In this context, five different fractions (bark, wood, branchlets, leaves, and flowers) of Acacia dealbata\u2014an invasive species\u2014were evaluated as fillers for premixed gypsum mortars, at 5% and 10% (vol.) addition levels and fixed water content. Although these biomass fractions had different bulk densities (&gt;50% of variation), all the mortars were workable, although presenting different consistencies. As expected, dry density decreased with biomass addition, but, while mortars with addition at 5% presented a slight shrinkage, a slight expansion occurred with those with 10% addition. Generally, the mechanical properties decreased with the biomass additions even if this was not always proportional to the added content. The wood fraction showed the most positive mechanical results but flexural and compressive strengths of all the tested mortars were found to be higher than the lower standard limit, justifying further studies.<\/jats:p>","DOI":"10.3390\/buildings12030339","type":"journal-article","created":{"date-parts":[[2022,3,11]],"date-time":"2022-03-11T12:58:36Z","timestamp":1647003516000},"page":"339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Gypsum Mortars with Acacia dealbata Biomass Waste Additions: Effect of Different Fractions and Contents"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6479-8678","authenticated-orcid":false,"given":"Alessandra","family":"Ranesi","sequence":"first","affiliation":[{"name":"CERIS\u2013Civil Engineering Research and Innovation for Sustainability, NOVA School of Science and Technology, NOVA University of Lisbon, Quinta da Torre, 2829-516 Caparica, Portugal"},{"name":"National Laboratory for Civil Engineering, Avenida do Brasil 101, 1700-066 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0372-949X","authenticated-orcid":false,"given":"Paulina","family":"Faria","sequence":"additional","affiliation":[{"name":"CERIS\u2013Civil Engineering Research and Innovation for Sustainability, NOVA School of Science and Technology, NOVA University of Lisbon, Quinta da Torre, 2829-516 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4301-9222","authenticated-orcid":false,"given":"Ricardo","family":"Correia","sequence":"additional","affiliation":[{"name":"METRICs, Department of Science and Technology of the Biomass, NOVA University of Lisbon, Quinta da Torre, 2829-516 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Teresa","family":"Freire","sequence":"additional","affiliation":[{"name":"CERIS\u2013Civil Engineering Research and Innovation for Sustainability, SIVAL-Gessos Especiais Lda, Rua Em\u00eddio Oliveira Faria, 2425-879 Souto da Carpalhosa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7135-8603","authenticated-orcid":false,"given":"Ros\u00e1rio","family":"Veiga","sequence":"additional","affiliation":[{"name":"National Laboratory for Civil Engineering, Avenida do Brasil 101, 1700-066 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0940-519X","authenticated-orcid":false,"given":"Margarida","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"METRICs, Department of Science and Technology of the Biomass, NOVA University of Lisbon, Quinta da Torre, 2829-516 Caparica, Portugal"},{"name":"VALORIZA, Polythechnic Institute of Portalegre, Campus Polit\u00e9cnico, 7300-555 Portalegre, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"456","DOI":"10.1016\/j.rmed.2008.09.011","article-title":"Cold temperature and low humidity are associated with increased occurrence of respiratory tract infections","volume":"103","author":"Juvonen","year":"2009","journal-title":"Respir.
