Its historical use has been linked to ornamental elements, although more recent research is oriented towards the industrialisation of plaster composites and the design of prefabricated parts for false ceilings and interior partitions. In this work, the behaviour against water of four new plaster-based composite materials is studied, using additions of two types of super absorbent polymers (sodium polyacrylate and potassium polyacrylate) and a lightening material (vermiculite) in their manufacturing process. In addition, the transmission of water vapour through the samples was studied together with the water absorption capacity of the samples in order to check the suitability of the use of plaster-based materials exposed to these environments. The results of this study show that composites with the addition of super absorbent polymers as well as vermiculite significantly improve their water performance compared to traditional materials up to 7.3% water absorption with a minimal (13%) reduction in mechanical strength compared to current materials with similar additions. In this sense, a plaster material is obtained with wide possibilities of application in the construction sector that favours the development of sustainable and quality buildings, in line with Goal 9 for Sustainable Development included in the 2030 Agenda.<\/jats:p>","DOI":"10.3390\/ma16020872","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T06:52:10Z","timestamp":1673851930000},"page":"872","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Characterization and under Water Action Behaviour of a New Plaster-Based Lightened Composites for Precast"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1032-1994","authenticated-orcid":false,"given":"Manuel","family":"\u00c1lvarez","sequence":"first","affiliation":[{"name":"Departamento de Tecnolog\u00eda de la Edificaci\u00f3n, Escuela T\u00e9cnica Superior de Edificaci\u00f3n, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Ferr\u00e1ndez","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00eda de la Edificaci\u00f3n, Escuela T\u00e9cnica Superior de Edificaci\u00f3n, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Guijarro-Miragaya","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00eda de la Edificaci\u00f3n, Escuela T\u00e9cnica Superior de Edificaci\u00f3n, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6928-5134","authenticated-orcid":false,"given":"Carlos","family":"Mor\u00f3n","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00eda de la Edificaci\u00f3n, Escuela T\u00e9cnica Superior de Edificaci\u00f3n, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"120800","DOI":"10.1016\/j.conbuildmat.2020.120800","article-title":"Development of plaster foam for thermal and acoustic applications","volume":"262","author":"Arroyo","year":"2020","journal-title":"Constr.
