“…The sludge generated by diamond blades or gang saws amounts to several millions tonnes worldwide annually. Despite an intensive search for potential industrial applications of this waste as an additive in concrete (Almeida et al 2007a, b) and/or a raw material for synthesis of refractories (Cheng et al 2002) or other materials (Cheng & Hsu 2006), residual sludge from dimension stone processing is still treated as waste (Barrientos et al 2010) that must be sent to landfill (Karaca et al 2012). Dino et al (2015) argue that, owing to the effort to minimize waste production during the processing of valuable raw materials, residual sludge from dimension stone processing can be used in several interesting applications such as landfill proofing or cover, filler for civil engineering works or as artificial soil for the rehabilitation of disused quarries, which is an excellent application of the 'cradle-to-cradle' principle.…”

Inorganic raw materials, here termed geomaterials, derived from the Earth's crust and used in construction after appropriate processing make a genetically and functionally varied group of mineral resources. Although their basic functions have remained almost unchanged for centuries, some new attributes, meanings and impacts on society are still emerging. Geomaterials for construction were among the first mineral raw materials exploited, processed and used by man. They helped in the development of technological and artistic skills of humankind. Accessibility, workability and serviceability are considered here as their main functional attributes, being connected with man's skills to find their occurrence, extract and process them, and then use them in the correct way. However, serviceability is a more complex functional attribute as it also encompasses durability of a material in construction. Durability, that is the ability to withstand the action of weathering/decay processes, is an expression of the dynamic interactions between material and the surrounding environment encompassing not only gradual adaptation of materials to current environmental conditions, but also interactions between materials in construction, the history of maintenance/conservation of the structure and the impact of a polluted environment. In the modern world, sustainable use of raw materials, specifically those exploited in the largest volumes such as geomaterials for construction, raises questions of reducing extraction of primary resources and thus minimizing impacts on natural systems, and also employment of materials and technologies to produce less emission of deleterious substances in to the atmosphere. Use of secondary materials such as waste produced during extraction of primary raw materials and/or re-use of existing structural elements and re-or down-cycling can be considered as modern approaches to reducing the pressure on primary resources.

“…Th ey contribute to higher strength of the materials similarly to steel reabrs in concrete. Although wollastonite and chrysotile are useful for the best quality of the artifi cal marble but chrysotile is considered to be carcinogenic so it is not preferred for the production of the cultured marble [7,8].…”

Large quantities of marble blocks are produced from many new marble quarries which were opened around Isparta (Turkey) and its surrounding region. The opened quarries are also affected negatively by weathering as a result of karstification. Therefore, block efficiency of the quarries is low which results in a lot of waste materials that can be used in cultured marble production. The production of artificial marble from marble waste materials around Isparta is the main purpose of the study. The cultured marble is an attractive, healthy and homogenous building material. It has a wide application in the building construction sector. Artificial marble which is composed of mineral dusts and polyesters has high mechanical strength and they are durable to various chemical and high temperature environmental conditions. Based on physico-mechanical properties, cultured marbles are accepted by Turkish Standards (TS). The materials used for the production of qualified cultured marble are directly related to the hardness of the minerals used as filler in the polyester resin. Physico-mechanical properties of cultured marble depend on the physical properties of the filler minerals. The compressive strength of the cultured marble material is controlled by the physical properties of the filler minerals, therefore, the hardness of the cultured marble is determined by the hardness of the filler mineral. The following analyses were carried out: wet unit volume analysis, dry unit volume analysis, compressive strength of the materials, capillary water absorption analysis, analysis of ultrasound velocity (P-wave) and the marble wastes bulk chemical analyses were investigated and the results of the data were evaluated and discussed. In addition, natural and artificial marbles were compared with respect to physico-mechanical properties.

High-quality forsterite ceramics were successfully prepared using desert drift sands to replace the traditional materials at lower temperatures, which not only saves mineral resources but also greatly reduces the cost of ceramic. Meanwhile, the effects of two different proportions of drift sands on the phase formation, physical and mechanical properties of ceramics were also investigated. The experimental results show that drift sands with impurity cations have the lower melting temperature compared to the pure quartz and easy to form liquid phase. As a result, the formation temperature (800°C) of forsterite phase falls by 300°C compared to the forsterite ceramic prepared using analytical reagent (1100°C). Furthermore, drift sands as raw materials can effectively improve the physical and mechanical properties of forsterite ceramics. Finally, the content of forsterite phase can reach up to 95.70 wt %, and the obtained forsterite ceramics show the best physical and mechanical properties when sintered at 1300°C for 2 h.
