“…The provided results are consistent with previous studies on the use of natural pozzolana and perlite in concrete production (e.g., [22]), where the addition of natural pozzolana and perlite improved certain mechanical properties and durability of blended cement. Hence, the study shows that natural perlite can be used as a partial replacement of cement for mortar production.…”

“…In this study, the so-called optimal mass substitutions of cement by natural pozzolana and perlite powders are determined based on previously established results available in the literature, with a maximum substitution level of 20% [22,23]. These natural materials will be combined in varying proportions to achieve the desired properties of the final mortars.…”

In this study, mineral materials sourced from northwest Algeria are examined as a specific case study. The main focus is on evaluating the feasibility of incorporating natural pozzolan and perlite as eco-friendly alternatives to traditional cement in the composition of mortar. The study involves assessing the mechanical properties and water absorption of the mortars at different time intervals. Additionally, scanning electron microscopy is employed to scrutinize the compositions and structures of the mortar. While mortars with pozzolanic elements initially exhibited reduced strength compared to the reference mortar, enhancements became evident over time. Despite a higher water absorption rate in pozzolanic mortars, the addition of 10% perlite resulted in the least absorption among all pozzolanic mixes. The research underscores the potential of natural pozzolan as an eco-friendly substitute for cement in mortar applications, emphasizing its viability and substantial contributions to environmentally conscious construction practices.

“…De nombreux travaux de recherches ont été récemment menés sur l'utilisation de la perlite dans le domaine du génie civil. Ces études ont porté sur la caractérisation physico-chimique, mécanique (Guenanou et al, 2019;Hamadache et al, 2016;Ayed et al, 2022).et la durabilité (Chihaoui et al, 2022;El Mir., 2020). révélant la possibilité d'utilisation de cette perlite (substance d'origine volcanique) en tant qu'ajout cimentaire pouzzolanique (Chikouche et al, 2016;Chaib et al, 2018).…”

Le sol algérien est riche en matériaux pouzzolaniques naturels, tels que la perlite naturelle, dans la région ouest plus précisément Hammam Boughrara à Maghnia (Tlemcen). 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.

In Algeria, the calcined dam's mud is a local renewable waste that proved its use as a supplementary cementitious material (SCMs) with similar mechanical performances and better resistance to several physical and chemical attacks than Portland cement. In the same context, the main objective of the work is to evaluate the effect of this calcined mud on thermal conductivity, which was never tested. To concretize this goal, one mortar based on control cement (CEMI) and three others based on modified cement by replacing CEMI by 10% to 30% Wt rates with the calcined mud of Chorfa dam have been prepared and cured before being put to the test procedure. Compressive strength, apparent density, water absorption after immersion, and thermal conductivity at three degrees of saturation state (saturated, outdoors, and dried state) were tested. The results show that using 10% to 20% replacement rate is characterized by good free lime and calcium hydroxide consumption that produces C-S-H gel, fills pores, decreases porosity, and increases density. The thermal conductivity of mortars based on the calcined mud in all states was lower compared than the control mortar, at saturated state by 16.28%, 17.83%, and 18.60% for the mortars 10%, 20%, and 30% (of cement replacement) respectively, at outdoors state by 5.5%, 4%, and 17.5% and dry state with 8.39%, 20.65%, and 38.07%. 10% to 20% mud replacement is beneficial for use in masonry and plastering wall applications of a building's envelope. 30% replacement rate can be developed and used in environments with minimal class expositions.
