“…In the formulation of concrete, others use fly ash [Wasserman and Bentur, 1997] or rice husk ash and coal bottom ash [Bheel et al, 2021] or newsprint ash [Wong et al, 2022], and they have also studied the physicochemical properties [Khudhair et al, 2018;Khudhair et al, 2017], thermal parameters, microstructural and acoustic parameters [Becker et al, 2022], fire resistance [Alireza et al, 2021], or have conducted research on the pre-wetting of clay aggregates and its effect on durability [Musial et al, 2021], liquefaction attenuation [Ghorbani et al, 2021] and also on the flexural strength of lightweight concrete [Baronet et al, 2022]. The lightweight concrete mix was performed according to the world standards as it has been done in several studies before [Melanie, 2003;Bogas et al, 2014].…”

In this work, marl clay was used because these materials have a very important industrial potentiality in several fields, namely ceramics. The objective was manufacturing expanded clay aggregate (ECA), with two main ingredients of marl and pozzolan at different percentages in order to integrate them into the concrete as aggregate. The physicochemical parameters of the mixture marl / Pozzolan was discussed and the results of the analyses, allowed deducing that the sample with 15% pozzolan has the most expansion rate of 16.8%, and its density of 1232 kg/m 3 is in accordance with the international standard of expanded aggregates. The density of the concrete decreases with the quantity of ECA added and reaches its minimum with 1671 kg/m 3 according to concrete with 50% of the expanded aggregate. The bending tests show the increase of the mechanical strength as a function of the quantities of aggregate added. The results show a very important potential with the addition of clay aggregates, density and water absorption decrease with the increase of the mechanical resistance.
