Ash from thermal power plants as secondary raw material.
The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as heating value, moisture, and mineral content, resulting in different residue upon combustion. Because of several million tonnes of ash and slag generated every year, their gran...
متن کاملThermal Properties of High-Volume Fly Ash Mortars and Concretes
As sustainability moves to the forefront of construction, the utilization of high volume fly ash concrete mixtures to reduce CO2 emissions and cement consumption per unit volume of concrete placed is receiving renewed interest. Concrete mixtures in which the fly ash replaces 50 % or more of the portland cement are both economically and technically viable. This paper focuses on a characterizatio...
متن کاملTreatment of fly ash from power plants using thermal plasma
Fly ash from power plants is very toxic because it contains heavy metals. In this study fly ash was treated with a thermal plasma. Before their treatment, the fly ash was analyzed by many technics such as X-ray fluorescence, CHN elemental analysis, inductively coupled plasma atomic emission spectroscopy and scanning electron microscopy. With these technics, the composition, the chemical and phy...

15 صفحه اولThermal Behaviour of Metakaolin/Fly Ash Geopolymers with Chamotte Aggregate
Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200 to 1200 °C on the mechanical properties and microstructure of geopolymers based on two different aluminosilicate precursors, metakaolin and fly ash. Moreover, the paper is also aimed at characterizing the effect of c...
