Nowadays, environmental problems and energy saving have been considered a serious situation due to the increase of industrial waste. In this research work, the mechanical properties such as compressive strength and flexural strength of bricks made from the raw materials clay, waste glass and sand were evaluated in order to reduce the sintering temperature and pollutant effects. The semi-products were sintered in an air atmosphere at a temperature of 800 °C for 8 h in a muffle at a rate of 10 min/°C. The chemical characterization of the raw materials was investigated by X-ray diffraction (XRD) and X-ray fluorescence (XRF), respectively. The microstructure of the bricks was analyzed by field emission scanning electron microscopy (FESEM). According to the experimental results in the mechanical tests of the bricks showed that the compressive strength of 43.55 MPa was higher than those indicated in the NMX-C-404-ONNCE-2012 standard. A flexural strength of 6.69 MPa highest than that specified in ASTM C1161-02c was also obtained.

摘要

Nowadays, environmental problems and energy saving have been considered a serious situation due to the increase of industrial waste. In this research work, the mechanical properties such as compressive strength and flexural strength of bricks made from the raw materials clay, waste glass and sand were evaluated in order to reduce the sintering temperature and pollutant effects. The semi-products were sintered in an air atmosphere at a temperature of 800 °C for 8 h in a muffle at a rate of 10 min/°C. The chemical characterization of the raw materials was investigated by X-ray diffraction (XRD) and X-ray fluorescence (XRF), respectively. The microstructure of the bricks was analyzed by field emission scanning electron microscopy (FESEM). According to the experimental results in the mechanical tests of the bricks showed that the compressive strength of 43.55 MPa was higher than those indicated in the NMX-C-404-ONNCE-2012 standard. A flexural strength of 6.69 MPa highest than that specified in ASTM C1161-02c was also obtained.
