The safe disposal of cement dust costs a lot of money and still pollutes the environment. Because of the high alkalinity of the cement by-pass dust, it can be used in the treatment of the municipal sewage sludge, which is considered another environmental problem in developing countries since it contains parasites such as Ascaris and heavy metals from industrial waste in the city. His main research topic is sustainable construction, particularly on the use of recycled aggregates in concrete and mortars. The main pollution source generated from cement industry is the solid waste called cement by-pass dust, which is collected from the bottom of the dust filter. Finally, the slag is placed in a water pool and cooled to around 60 °C to complete the process and it is sent for magnetic screening to separate the iron fraction. The global cement industry contributes around 6% of all man-made CO2 emissions and is consequently responsible for around 4% of man-made global warming. Options for blended cements include fly ash and steel slag. The main energy consumption (in 109 kJ) are for: raw grinding = 8.346 (1.88%), kiln heating (fuel combustion) = 410.464 (92.68%), and finish milling = 24.057 (5.43%) [22]. He earned his PhD.
