“…However, at 1,000°C, compositions with 40 % of bottom ash showed greater density than the control mixture, and those with 60 % of bottom ash were similar. Probably it is because the sintering process took place at that temperature and this effect prevailed over the specific gravity [18]. Comparing both bottom ashes, results are very similar to each other for all the compositions, though mixtures of BB presented less density than BC compositions, probably due to the lower specific gravity and higher LOI.…”

“…3, 4 and 5. As the firing temperature was increased, the products showed a greater density in all the cases due to the increase in the sintering grade which makes the porosity decrease as well [18]. The products were less dense when the proportion of bottom ash added in the mixtures was higher, because of the lower specific gravity of the bottom ash than that of the NC.…”

The present investigation aims to analyse alternative uses of bottom ash and fly ash as part of construction materials for different applications: bottom ashbased ceramic bricks, pozzolanic material in the cement production, waste stabilisation/solidification of an electric arc furnace dust using ash-based geopolymers, and ashbased geopolymers used as hydraulic road binders. Different replacements of natural materials by different fly and/or bottom ashes have been studied in all the cases. This study has analysed various parameters influencing the manufacturing process, with the aim of reducing the energy consumption of these processes, as they have been, for example, the firing temperature of bricks and grind size of bottom ashes in cements. All materials are manufactured in a simple and economical way, in order not to increase the cost of the products, and the final products have been evaluated according to different European standards used in these applications, in order to assess their possible, actual technical feasibility. The results obtained in this study show that even higher ratios of replacement ([40 %) of ashes have properties similar to those commonly used.

“…The concentrations of the heavy metals were presented in Table I. As a result, it showed that the heavy metals in raw materials were below the thresholds prescribed in Soil Quality Standard of Pollution Control Department [13]. Therefore, dredged sediments could be used as raw materials for producing bricks without harmfulness.…”

Abstract-The laboratory-scale study was conducted to assess the feasibility of using dredged sediments from Lumsai canal with rice husks to produce bricks. This study was investigated into three different proportions of dredged sediments with rice husks ranging from 0, 5, 10, 15, and 20 percent (by weight of rice husks or rice straws) as raw materials in producing bricks. The characteristics of the dredged sediments, rice husks, and fired bricks were analyzed using X-ray fluorescence (XRF) and X-ray diffraction (XRD), respectively. The physical-mechanical properties of fired bricks were found to comply with the criteria for bricks (Thai Industrial Standards 77-2545). The obtained results indicated that major chemical compositions of dredged sediments were silica (SiO 2 ) 56.27 percent, alumina (Al 2 O 3 ) 11.76 percent and iron oxide (Fe 2 O 3 ) 7.84 percent, and heavy metal contents including Cr, Cu, Zn, As, Cd, Hg, Pb, Mn, Sr, and Ni were lower than the soil quality standard. Results of this study showed that bricks made from dredged sediments with 5 percent of rice husks were suitable as primary raw materials in the production of bricks without harmfulness.Index Terms-Bricks, dredged sediments, rice husks.

Abstract. Blends of Tungsten mining waste mud (TMWM) and brick waste powder (BP) with different dosages were used as precursors for the study of a new binder obtained by alkali-activation. The synthesis was obtained at 60ºC curing during the first 24 hours and at 20°C during the remaining period. A combination of sodium hydroxide (SH) and sodium silicate (SS) solutions was used with SS/SH weight ratio equal 1.5. The solid precursors/liquid activators weight ratio equal to 4. And the modules SiO 2 /Na 2 O increase with the increasing of BP dosages 5.21 and 5.59 for dosages 10% and 50%, respectively. Mineralogical characterisation of raw materials was carried out by X-ray diffraction (XRD). The effect of the dosage of BP on the compressive strength and pore size distribution of the new binder was investigated from 24 hours up to 28 days. The pore size distribution was obtained mercury intrusion porosimetry (MIP). The increase in the dosages of BP, between 10 to 50%, was followed by an increase in compressive strength, from 25 to 59 MPa, for all the tested ages. The binder matrix become more dense and compact with the gradually increase of BP dosages, as found out by MIP.
