10 07 2019 When cement contents are reduced in the fly ash or slag mixture the bleeding value reduced sharply For example the bleeding values of mix C mix S30 and mix FA30 are and respectively It can be explained by the fast demulsification process of asphalt emulsion in the mixture with only cement.
heating are generated However during this process two hazardous by products are formed namely slag and fly ash These contain relatively high concentrations of heavy metals which make them harmful to the environment if not taken care of but also make them valuable resources if the metals could be extracted and reutilized.

coal fired power plants and different steel plants it is necessary to urgently seek solutions to consume coal slag fly ash and blast furnace slag which continue to arise and exist in the storage areas Based on the above problems the goal of our research was to optimize the production process of coal and metallurgical slag based geopolymers 2.
heating are generated However during this process two hazardous by products are formed namely slag and fly ash These contain relatively high concentrations of heavy metals which make them harmful to the environment if not taken care of but also make them valuable resources if the metals could be extracted and reutilized.
Slag is similar to fly ash in that it is finer than standard Portland cement and is also cheaper as it is a process byproduct It is is produced by the steel production industry Slag happens when iron ore is melted.
