“…The best resistant products are most often characterized by an assembly of coarse grains (over 70%) and fine grains. In this study, the presence of a large amount of the Fireclay (66%) in the formulations with a particle size mostly in the range 0.5‐3.0 mm (92%), results in a high compressive strength (similar to samples processed between 1400 and 1500°C as reported by MS Elmaghraby et al 33 ) and a lower modulus of elasticity, and thus lower bending strength.…”

In industry, the refractory materials, generally resistant to high temperatures (>1500°C), are considered of great importance for thermal insulation and for the manufacture of furnaces. Fired bricks or unshaped materials (monolithic materials) are usually used for applications involving high temperatures in corrosive conditions (such as the presence of oxidizing or reducing agents), including the ceramic industry, iron and steel industry, non-ferrous metallurgy, petrochemical, cement and glass industry, incinerators, and energy production. The new feature requirements taking into consideration the working environments for better performance and lower production cost of the raw materials, are considered the main focus of numerous recent studies. The essential category of traditional refractory products is fireclay, with a high content of Alumina and Silica. The choice of material for traditional refractory and advanced materials' applications has been carried out based on the optimization between cost, quality and performance taking into consideration the working environments. Kaolin, the basic raw material for the production of Silica-Alumina refractories, is derived from the hydrothermal alteration of alkaline Granite which causes the kaolinization of alkali-feldspar of Granite rock and produces a friable aluminous material 1 : Feldspar Kaolin. This research work contributes to the development of local natural resources and to prospect the potentialities of 6SiO 2 2 O 3 K 2 O + 2H 2 O + CO 2 → 2SiO 2 2 O 3 2H 2 O + 4SiO 2 + K 2 CO 3

Abstract. This study aims to improve the thermal of insulation properties of fired bricks based on clay from the Drâa-Tafilalet region (Es-sifa), using coffee waste without losing mechanical properties. Samples were produced on a laboratory scale by shaping, similar to a feasible industrial production technique. The raw material was first characterized using various analytical techniques such as XRD and TGA/DTA. Secondly, we optimized the main parameters affecting the properties of the bricks, such as particle size, aging time, drying time, final sintering temperature and the percentage of agent porosity. These parameters are assessed by mechanical strength and porosity tests. Examination of results the optimization following results: the particle size is less than 180 µm, the aging time and the drying time are three and four days respectively, while the sintering temperature is 1050 °C and the percentage of coffee waste used as a porosity agent is 4%. Introducing coffee waste to the brick reduces weight and improves thermal and acoustic properties by creating pores during firing. These results are very promising for exploiting these materials as base materials in the manufacture of building bricks with important properties.

“…Elmaghraby M. S. and Ismail A. I. M. explored the chemical, mechanical, and mineralogical properties of the waste kaolinitic sand used to prepare concrete. According to their test results, some mixtures can be used in industrial furnaces at 1500 °C in order to produce concrete [ 43 ]. In summary, it is worth emphasizing that the use of waste marble powder for the production of many types of concrete would be beneficial for the natural environment due to the positive aspect of waste disposal.…”

An Experimental and Empirical Study on the Use of Waste Marble Powder in Construction Material

et al. 2021

Marble is currently a commonly used material in the building industry, and environmental degradation is an inevitable consequence of its use. Marble waste occurs during the exploitation of deposits using shooting technologies. The obtained elements most mainly often have an irregular geometry and small dimensions, which excludes their use in the stone industry. There is no systematic way of disposing of these massive mounds of waste, which results in the occurrence of landfills and environmental pollution. To mitigate this problem, an effort was made to incorporate waste marble powder into clay bricks. Different percentage proportions of marble powder were considered as a partial substitute for clay, i.e., 5–30%. A total of 105 samples were prepared in order to assess the performance of the prepared marble clay bricks, i.e., their water absorption, bulk density, apparent porosity, salt resistance, and compressive strength. The obtained bricks were 1.3–19.9% lighter than conventional bricks. The bricks with the addition of 5–20% of marble powder had an adequate compressive strength with regards to the values required by international standards. Their compressive strength and bulk density decreased, while their water absorption capacity and porosity improved with an increased content of marble powder. The obtained empirical equations showed good agreement with the experimental results. The use of waste marble powder in the construction industry not only lowers project costs, but also reduces the likelihood of soil erosion and water contamination. This can be seen to be a crucial factor for economic growth in agricultural production.
