This paper demonstrates the possibility of producing new red ceramics composites from red mud of hazardous bauxite waste (50?100 wt%), and foundry sand (10?50%) replacing the traditional clay-sand mix and preventing the environment pollution by such industrial wastes. The newly developed environment-friendly ceramics exhibit high physical properties (flexural strength, linear shrinkage, water absorption, and density). The ceramics? analysis by X-rays fluorescence, X-rays diffractometry, atom absorption spectroscopy, scanning electron microscopy, energy-dispersion spectroscopy, and laser micro-mass analysis revealed the synthesis of mainly glass-like structures with a small inclusion of crystalline structures. The values of flexural strength reached 10.54 MPa; after sintering at 1150 C, linear shrinkage varied between 6.62 and 7.92%, water absorption ? 2.77 and 14.41% and bulk density ? 1.65 and 2.07 g/cm3. The most valuable property of the developed materials is the ecological purity due to the heavy metal?s complete neutralization from both industrial wastes. |

The objective of this study was to evaluate the effects of supplying the by-product of peach-palm (Bactris gasipaes) on performance and characteristics of carcass and non-carcass components of feedlot lambs. Twenty Santa Ines lambs of 150 days average age and 22.4±3.4 kg body weight were confined in individual pens. A completely randomized design was utilized with four experimental diets composed of: fresh peach-palm by-product enriched with urea, fresh peach-palm by-product + concentrate, silage of peach-palm by-product + concentrate, and silage of peach- palm by-product enriched with 15 % corn meal + concen- trate. Intake was evaluated daily, and at the end of 42 days of experiments, lambs were slaughtered and the characteristics of carcass and non-carcass parts were evaluated. Performance and carcass characteristics showed differences between the animals? intake of total mixed rations (TMR) and only the diet with roughage. For the lambs that intaked TMR, the form of utilization of roughage (fresh or as silage) affected animal performance but did not change the carcass characteristics. Dry matter intake and feed conversion were influenced by the form of utilization of the silage (with and without additive). Providing fresh by-product plus concentrate improves lamb performance but does not interfere in the carcass characteristics, compared with the use of by-product in the form of silage. |
