“…The results of Young's modulus obtained for the samples fired at 900 °C (E=61 GPa) compared to other glass ceramics in literature, confirmed similar properties [42]. The ratio of Young's modulus to bending strength was of the order of 1000 in agreement with that of most ceramic materials [43].…”

This paper reports the results of a study focused on the obtainment of glass-ceramic by using rice husk ash (RHA) as silica precursor. RHA is a by-product generated in biomass plants using rice husk as fuel for kilns or in the rice mills to generate steam for the parboiling process.Worldwide, it is annually produced about 132 Mt of rice husk, which gives rise to a production of 33 Mt/year of RHA. Glass-ceramic tiles were produced by a sinter-crystallization process using a glassy frit formulated in the MgO-Al 2 O 3 -SiO 2 composition system. The realized glassceramics were studied according to ISO rules for sintering and technological properties (water absorption, apparent density, bending strength, Young's modulus, deep abrasion, Mohs hardness). To complete the investigation crystalline phase formation and microstructural characterization of the glass-ceramic materials was carried out using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Finally, chemical durability tests on parent glass and derived glass-ceramics were performed. The results obtained showed that it is possible to use RHA to produce glass-ceramic tiles by a sinter-crystallization process, obtaining nepheline (Na 2 O*Al 2 O 3 *SiO 2 ) as main crystalline phase and forsterite (2MgO*SiO 2 ) at 900 °C. Regarding technological features, the sintered materials showed bending strength values and Mohs hardness higher with respect to commercial glass-ceramics like NeopariesR. Other properties as water absorption (0.5%) allowed to classify these materials into the Group BIa characteristic of high sintered ceramic tiles according to European Standard rule.

“…Before use, bottom ash has to be oven dried and ground in order to improve homogeneity. It has been established that it is possible to manufacture glass-ceramics from bottom ash and from bottom ash mixed with other wastes, namely glass cullet and steel fly ash [151,[154][155][156][157][158], and this will be considered in more detail here.…”

Glass-ceramics: Their production from wastes—A Review

2006

View full text Add to dashboard Cite

Glass-ceramics are polycrystalline materials of fine microstructure that are produced by the controlled crystallisation (devitrification) of a glass. Numerous silicate based wastes, such as coal combustion ash, slag from steel production, fly ash and filter dusts from waste incinerators, mud from metal hydrometallurgy, different types of sludge as well as glass cullet or mixtures of them have been considered for the production of glass-ceramics. Developments of glassceramics from waste using different processing methods are described comprehensively in this review, covering R&D work carried out worldwide in the last 40 years. Properties and applications of the different glass-ceramics produced are discussed. The review reveals that considerable knowledge and expertise has been accumulated on the process of transformation of silicate waste into useful glass-ceramic products. These glass-ceramics are attractive as building materials for usage as construction and architectural components or for other specialised technical applications requiring a combination of suitable thermo-mechanical properties.

“…Kula et al [31] reported that y ash and coal bottom ash can be used as a high volume cement replacement in the production of concrete. MSWI ash or bottom ash was used for di erent applications; for instance, as raw materials for clinker production [32] and for cement production [20,21,23,33], as aggregates in nonstructural concrete [34], as controlled low-strength materials in trench construction [35] and in the production of polymer concrete [36], as aggregates in road construction and in concrete [16,37,38], as in the form of glass-like as natural aggregates in mortar and concrete [19], in tile production [39], and in glass ceramic products [40].…”

Abstract. Petrochemical wastes incinerator ash is generated from industries in which the land ll is the last step for their owing. This research was performed for waste management of ash and its possible large-scale utilization in making concrete. An experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which Portland cement type II was partially replaced with Petrochemical Complex Incinerator Ash Powder (PCIAP). The cement was replaced with various amounts of PCIAP, i.e. 5%, 10%, 15%, 20%, and 25%. Tests were performed on the properties of fresh concrete as well as hardened concrete. Compressive, splitting tensile and exural strengths, and modulus of elasticity were determined in 7, 28, and 90 days. Test results indicated that by using PCIAP as partial replacement of cement, stabilization, solidi cation, and neutralization treatment processes for the industrial wastes management were carried out, and the test results of the mixture M-2 (5% PCIAP) indicated that it can be used to make concrete which is lighter than normal concrete and heavier than structural lightweight aggregate concrete.
