Recycling of slag in the pelleting process is a big question even though the slag contains high amount of CaO and MgO that would be useful for the pellets; the pellet would stably maintain the blast furnace slag chemistry.
The attentions have been payed for the factors such as porosity, structure, etc. that affects the reducibility of the pellet.

Currently, the main application is injection molding and reaction, which gave impetus to studies related to the molecular structure and properties of polyurethanes [2].
Vilar, Chemistry and technology of polyurethanes.

This is due to the absence of activated fly ash (AFA) & activated bentonite (AB) at the far end of the reaction due to the thermal instability of alumina-silicate structure at high temperatures.

According to Liu [19] additive interactions leading to repulsion and interfacial structure mismatch of the nucleating phase with a nuclei result in a higher value of the critical energy.

If the MDA density is elevated, it not only may directly destroy cell component, but also can simultaneously activate the lipin peroxidation once again and further damage the cell structure and the function, cause the muscle working ability to drop, then influence exercise ability.
