“…In short, the water retention capacity and the flexural strength of the bricks showed positive changes with the simultaneous addition of fly ash and acidic process waste water into brick material when compared to the standard bricks composed of clay alone. These findings are in a good agreement with the findings of other work in the literature [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Among these studies, for example, Kute and Deodhar [22] showed that the compressive strength of bricks baked at a certain temperature can be improved by 4-5 times for some proportions of fly ash.…”

a b s t r a c tFly ash contains metals such as cadmium, iron, lead, aluminum and zinc in its structure in appreciable amounts. These metals can leach out into surface and ground waters if fly ash is not properly disposed of. A similar problem also exists for acidic process waste waters discharged by numerous industries. The purpose of this study was to utilize such wastes as additives in the production of construction quality bricks for the purpose of waste elimination. The bricks produced were subjected to flexural strength and water retention capacity tests along with heavy metal leaching experiments in order to determine the applicability of the procedure and the best possible recipes. This paper summarizes the results obtained in these tests along with the possible mechanisms involved in stabilizing the two wastes in the brick structure.

“…There is also a large body of work on the utilization of fly ash in cement and brick production [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. These studies mainly focus on the effect of fly ash addition on the structural behaviour of the final products.…”

“…Consequently, the incorporation of industrial wastes or subproducts in bricks and tiles is becoming a frequent practice in the ceramic factories. In this sense, it has been conducted several studies in last years concerning the production of bricks with the incorporation of both organic [15][16][17] and inorganic wastes, such as, sewage sludge ash [18][19][20], waterworks sludge [21], natural stone wastes [22][23][24][25][26], fly and bottom ashes [27][28][29][30][31][32][33][34], metallurgical wastes [35][36][37][38] and boron waste [39,40].…”

The effect of the heating temperature on the properties of sintered ceramic bodies from three different contaminated marine sediments was investigated. The sintering behaviour was evaluated by means of the variation of shrinkage degree, bulk density, water absorption, open and closed porosity, while the phases transformation were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results have shown that the sintering process follows a viscous liquid phase mechanism due to the formation of a glassy phase. The optimum sintering temperature is 1125ºC for Astilleros and Cuchia sediments and 1150ºC for Raos sample. Above this temperature, a significant overfiring with an increase of closed porosity was observed. Water absorption values and mechanical properties as bending and compressive strengths of sintered bodies show that the investigated marine sediments are suitable to be used as secondary raw materials in ceramic tiles and bricks production.

“…Higher additions reduce the compressive strength and deteriorate the surface of the bodies. Kavas [7] reports that introducing clay and fine boron wastes up to 15 wt.% in mixtures with Bayer's process red mud, results in the formation of glassy phase improving the mechanical properties of the fired bodies. Kurama et al [8], studied a mixture consisting of dewatered sieve waste, ball clay and sanitaryware waste for the production of a terracotta floor tile body.…”
