The increasing production of coal fly ash waste from thermal power plants has compounded environmental and economical problems worldwide. Considerable research has been undertaken because of the environmental problems presented by the fly ash. The goal is to produce usable material from waste. The aim of this papier is to produce glass from fly ash and limestone that will have high resistance to dissolution and leaching. Obtained glass could have wide application in industry. Coal fly ash was mixed with 37% limestone and melted in electric furnace at T=1500 °C during t=1 h. The obtained glass sample was black, without visible residual gas bubbles. X-ray powder diffraction (XRD)analysis confirmed the quenched melt to be amorphous. To determine the chemical durability, glass sample was crushed and then sieved to grain size 0.3-0.5 mm. The corrosion test was performed in a distilled water, HCl and NaOH solution (0.01 M9 at T=95 °C for t=2h using 2 g of samples and 70 ml of solution. The r...esults of corrosion test revealed a high durability of the glass sample. Potential application of this material would include use as: building blocks, anticorrosive container lining, matrix material in which radioactive wastes and heavy metals could be successfully solidified into the glass structure.
