“…It is used for various industrial applications (ceramics, inks, purification oils, pharmaceuticals, paper, paint, oil industry, etc.). Clay is one of the most used industrial raw materials, the latest studies on the Miocene marls of Benjalik show an impressive potential, and they have been doped with MnO 2 , Fe 2 O 3 , and Al 2 O 3 [Mesrar et al, 2014[Mesrar et al, , 2021. Conventional concrete is very expensive, and causes irreparable damage to the environment, hence the idea of preparing a thermal insulation material with acceptable mechanical properties [Yew et al, 2021] On the other hand, the marl shrinks with the increase of temperature because the porosity created during the firing enables the gases released by the decomposition of carbonates and organic matter to escape [Allison et al, 1965].…”

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.

“…Both the Miocene marls from the Meknes region and the Fez marls are suitable for structural clay products (Mesrar et al , 2013). Furthermore, the Miocene marls from the Taza region (central northern Morocco) have a similar composition consisting of quartz, calcite, dolomite, illite and kaolinite (Mesrar et al , 2017).…”

Characterization of Neogene marls from the Kert Basin (northeast Morocco): suitability for the ceramics industry

et al. 2019

The Neogene marls from the lower Kert area (northeast Morocco) were characterized to evaluate their suitability for the ceramics industry. Two cross-sections involving all of the Neogene facies were studied on both banks of the Kert River. Grey and green marls occurring between sandstone and tuffs were characterized by mineralogical (X-ray diffraction) and physicochemical (grain size, Atterberg limits, X-ray fluorescence and specific surface area) analyses. The Neogene clays studied are mainly calcareous silty marls containing 13–20 wt.% calcite. They consist of quartz, calcite, feldspars, dolomite, illite, kaolinite, chlorite and 10–14 Å illite-vermiculite mixed layers. Cristobalite was detected only in the uppermost level of the green marls, and it originates from a volcanic ash of Messinian age. Trace amounts of siderite and rhodochrosite indicate reducing or locally oxidizing conditions during sedimentation or shortly thereafter. The marls have medium to high plasticity, making them optimal for extrusion. Raw Neogene marls are suitable for manufacturing structural clay products. More specific uses, such as hollow products, roofing tiles and masonry bricks, were supported by the geochemical results and grain-size distribution.
