Resumo: | The Algerian soil is rich in natural pouzzolanic materials, such as natural perlite, in the western region more precisely Hammam Boughrara in Maghnia (Tlemcen). Unfortunately, they’re not yet fully exploited. Perlite, thanks to its chemical components, silica and aluminum, which give it interesting properties, has the privilege of being used as an active mineral additiion in the production of cement. This study contributes to more data on the valorization of perlite as a partial substitute for cement. For this purpose, mortars containing different levels of perlite (0%, 10%, 15%, 20% and 25%) were manufactured. The behaviors of the five formulations in the fresh state (consistency, workability and setting time) and in the hardened state (capillary absorption, thermal conductivity and compressive strengths) were studied. The results of the experimental study prove that Maghnia perlite has a positive effect on the properties of mortars. The possibility of using it at dosages up to 25% in order to decrease the rate of cement implies an economic and environmental advantage. In addition, long-term satisfactory mechanical strengths behavior for a 20% perlite rate was noted. Furthermore, mortars containing perlite have low thermal conductivity, which highlights the beneficial effect of perlite as a thermal insulator and the importance of enhancing this addition. |

Malheureusement, ils ne sont pas encore totalement exploités. La perlite, grâce à ses composants chimiques en l’occurrence la silice et l'alumine qui lui procurent des propriétés intéressantes, s’octroie le privilège d’être utilisée comme un ajout minéral actif dans la production du ciment. Cette étude contribue à apporter plus de données relatives à la valorisation de la perlite comme substitut partiel au ciment. Pour ce faire des mortiers contenant différents taux de perlite (0%, 10%, 15%, 20% et 25%) ont été confectionnés. Les comportements des cinq formulations à l’état frais (consistance, maniabilité et prise) et à l’état durci (absorption capillaire, propriétés thermo-physiques et résistances à la compression) ont été étudiés. Les résultats de l’étude expérimentale prouvent que la perlite de Maghnia influe positivement sur les propriétés des mortiers. La possibilité de l’employer à des dosages allant jusqu’à 25% dans le but de diminuer le taux du ciment implique un avantage économique et écologique. Par ailleurs, un comportement mécanique à compression satisfaisant à long terme pour un taux de perlite de 20%, a été noté. En outre, les mortiers composés de perlite présentent de faibles conductivités thermiques ce qui permet de mettre en évidence l’effet bénéfique de la perlite comme isolant thermique et l’intérêt de valoriser cet ajout.Universidade Federal de Viçosa - UFV2024-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1880010.18540/jcecvl10iss3pp18800The Journal of Engineering and Exact Sciences; Vol. 10 No. 3 (2024); 18800The Journal of Engineering and Exact Sciences; Vol. 10 Núm. 3 (2024); 18800The Journal of Engineering and Exact Sciences; v. 10 n. 3 (2024); 188002527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVfrahttps://periodicos.ufv.br/jcec/article/view/18800/9677Copyright (c) 2024 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBelaribi, OmarSafer , OmarBelas, NadiaBelguesmia, KhalilHadj Sadok , Rachid2024-05-15T20:25:07Zoai:ojs.periodicos.ufv.br:article/18800Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2024-05-15T20:25:07Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
