“…The finer particle size leads to a denser microstructure, which ultimately increases the strength. The filler effect of marble powder is also confirmed by Alyousef et al while using it in self-compacting concrete [22]. Riaz et al carried out a similar study, involving the use of a fine filler material in place of clay in fire-burnt clayey bricks: They have observed similar increase in compressive strength of the finished blocks [23].…”

In this study, use of glass powder and marble powder as partial replacement of cement in various proportions (5%, 10%, and 15% by weight) in manufacturing of non-load bearing hollow concrete blocks is investigated. The manufactured blocks were evaluated for various characteristics as per ASTM C140/C140M, such as compressive strength, dry density and water absorption. Marble powder is obtained during sawing, cutting, shaping and polishing of marble, and it is normally rendered as solid waste. A huge quantity of discarded glass is dumped in landfills, world over. The mean dry densities of marble powder and glass powder used in this work are 2656.2 kg/m 3 and 2547.4 kg/m 3 , respectively, making them lighter than ordinary cement. The optimum value is found to be 10% replacement of cement (by mass) by the waste materials. It is found that the compressive strength increases by 40% and 18%, dry density decreases by 4% and 5% and water absorption increases by 28% and 36%, if 10% cement is replaced by marble powder and glass powder, respectively. It can be concluded from the results that the non-load bearing hollow concrete blocks with improved compressive strength and light weight can be manufactured by using glass powder and marble powder. Recycling of solid wastes like marble powder and glass powder in concrete is advantageous: It will not only address the waste management issues, but will also result in saving the quantity of cement in concrete, which itself is environmentally hazardous material.

“…It has been shown that, while reducing the environmental footprint, the addition of up to 30% of waste calcium carbonate does not negatively affect the materials’ properties (Valentini et al , 2020). Marble waste from Tunisian quarries has been used previously in the preparation of self-compacting concrete (Alyousef et al , 2018). Considering that marble production in Tunisia represents an important industrial sector (Ministry of Industry and SMEs, Republic of Tunisia, 2014) and that up to 60% of the gross production of waste occurs during marble quarrying, polishing and processing (Montani, 2017), the addition of this waste has potential for the development of sustainable binders based on locally sourced raw materials through adopting a circular economy approach.…”

Potential use of Kebilian clay reserves(southern Tunisia)for the production of geopolymer materials

The aim of this study was to help drive the Tunisian construction industry towards a more sustainable approach given the existence of abundant local raw material deposits that could be exploited for the production of low-CO2 binders. Various clay sediments from the Kebili region (southern Tunisia) were characterized by chemical analysis, X-ray diffraction, thermal analysis and geotechnical tests to determine their suitability for the preparation of geopolymer binders. The clays consist of illite and kaolinite with other accessory minerals. To test the possibility of using these materials as precursors for the production of low-CO2 and low-cost geopolymers, the raw samples were calcined and activated by addition of solid sodium silicate. Compressive strength tests performed on four alkali-activated clays show that promising mechanical performance may be achieved, with mechanical strength values as high as 25 MPa after 7 days, depending on the clay composition. The mechanical strength is related to the SiO2:Al2O3 and Al2O3:(NaO2 + K2O) ratios. Careful selection of the raw materials is, therefore, an essential step in the exploitation of clay deposits to be used for the production of ecological materials such as geopolymers.

The aim of this study is to assess the possibility of utilizing waste marble dust (WMD) as a partial cement substitution in air-cured mortar (ACM). Three different levels of cement replacement were analyzed: 5%, 10% and 15% by cement weight. The specimens were manufactured in a local laboratory at an air temperature of 22 ± 2 °C and a humidity equal to 20 ± 1%. The chemical and physical properties of ordinary Portland cement and WMD has been found to be the most crucial parameters. A variety of macroscopic tests, such as apparent density, porosity and compressive strength, were proposed in order to explain the effect of utilizing the WMD on the ACM. To confirm the results of the macroscopic properties, thorough microstructural analysis using scanning electron microscopy (SEM) was performed. The obtained results of this study indicate that replacing cement with WMD affects the physical and mechanical properties of air-cured mortar. The apparent density and compressive strength decrease while the porosity increases.
