“…For most samples, the range of variation of the LOI 1000 between 9˗12 % (at the exception of P1, LOI 1000 = 5.7 %) reveals the presence of mainly hydrated minerals such as clay and goethite [2]. High ratio of SiO2/Al2O3 (>3) and low LOI 1000 (5.7 %) in the sample from Pabre (P1) suggests an important contribution of quartz and low content of clay minerals [2,4].…”

The main objective of this study is to characterize the physico-chemical and mineral properties of clay materials from Burkina Faso to produce stabilized compressed earth blocks (CEBs). The reactivity of the clay materials was tested based on the electrical conductivity of solutions and the compressive strength of CEBs stabilized with 0-20 wt% CCR (calcium carbide residue) and cured for 45 days at 40±2 °C. Pabre and Kossodo respectively contain the highest fractions of clay (20-30%) and gravel (40%). Saaba and Pabre contain the highest content of kaolinite (60˗70%) and quartz (45-60%) and recorded the highest and lowest reactivity, respectively. The compressive strength of CEBs stabilized with 20% CCR improved tenfold (0.8 to 8.3 MPa) for Saaba and only 2.6 (2 to 7.1 MPa) for Pabre. The clay materials in the present study are suitable to produce CCRstabilized CEBs for load-bearing construction.

“…Clay materials for application in construction of modern buildings have been mostly studied for production of fired products such as tiles and bricks [1][2][3][4][5]. The firing process is energy consuming and therefore not environmental-friendly, resulting in relative increase of the cost and embodied energy of the products [6][7][8].…”

“…Ceramics stand as one of the most usual domains in which clays are used. The type and the quality of the end products depend on the sample characteristics such as mineralogy, physicochemical properties and chemical composition [1][2][3][4][5][6]. Amongst clays, kaolinite-rich clay deposits are widely spread and their occurrences are large in Cameroon [7].…”

Mineralogy and preliminary assessment of the potential uses of alluvial clays from Batouri (Eastern-Cameroon)

This study aimed at assessing the potential uses of alluvial clayey materials from Batouri. Their mineralogical, chemical and some physicomechanical characteristics are presented with some characteristics of fired bricks at 900, 950, 1000, 1050 and 1100 °C. The raw materials consisted of kaolinite, quartz, K-feldspars, anatase, and goethite. The phases formed during the firing process were mullite, quartz, hematite, and anatase. The linear shrinkage increased with firing temperature and remained <12% while water absorption decreased and remained <25%. Flexural strength increased due to the formation of dense phases (especially mullite) and, except for one sample, was at least 2 MPa. The SEM micrographs showed cracks that accounted for overall moderate mechanical responses. For firing above 1000 °C, the flexural strength of the three samples makes them usable as raw materials for roofing tiles manufacturing if the convenient amendment is done. The overall properties highlighted that all the studied materials are usable for brick manufacturing.

“…The high SiO 2 and low Al 2 O 3 contents might be associated with increased amounts of the clay minerals, quartz and feldspars (Kramar et al , 2012; Boussen et al , 2016; Milošević et al , 2016; Daghmehchi et al , 2018). The molar ratio of SiO 2 :Al 2 O 3 (3.41%) reflects the large contribution of quartz in the sample (Abdelmalek et al , 2017; Milošević et al , 2017, 2019a). The K 2 O (1.01 wt.%) is associated with the presence of minor K-feldspar or mica (illite or muscovite) (Monterio & Vieira, 2004; Celik, 2010), while the MgO (0.76 wt.%) is attributed to minor smectite or chlorite (Montana et al , 2011).…”

Mineralogical analysis of a clay body from Zlakusa, Serbia, used in the manufacture of traditional pottery

2020

The production of pottery in the traditional manner using local raw materials can provide insights into the provenance of ancient artefacts. This study uses mineralogical analysis to evaluate the raw clays and tempers used for pottery production in Zlakusa (western Serbia). Particle-size distribution, plasticity, X-ray fluorescence spectroscopy, X-ray powder diffraction, scanning electron microscopy/energy-dispersive X-ray spectrometry and differential thermal analysis techniques were applied. The mineral phases identified in the raw clay sample are kaolinite/halloysite, mica/illite, smectite, quartz, paragonite, feldspar, calcite and hematite. The clay body sample is a mixture of raw clay and crushed calcite in a ∼50:50 ratio, which was confirmed using various techniques. We have also considered and investigated the technological potential of the sampled materials, taking into consideration their actual and potential applications. It was confirmed that the clay body may be used in the manufacture of bricks and pottery, but its industrial application is limited by the paste recipe.
