Crushed coal. Crushed coal is used for the same purposes as gilsonite (i.e., for light weight and lost-circulation control). It is commonly used at concentrations up to 50 lbm/sk of cement. Its density is slightly higher (1.3 g/cm 3), requiring a slight increase in water content. The addition of bentonite to prevent separation is normally not ...

Concrete is a mix of several different materials: water, fine aggregates (or sand), coarse aggregates (or gravel), chemical additives, and, most importantly, cement. Cement is what binds all of these ingredients together to give concrete its durability and distinctive, grey appearance. Cement production, however, also generates most of …
The effect of CO 2 curing and coal gangue on sulfate attack of cement paste at low temperature was investigated in this paper. The strength change, mass change and volume deformation were analyzed. In addition, pore structure, phase composition and microscopic morphology were tested by using MIP (mercury intrusion porosimeter), TG …

This approach is significantly more energy-efficient compared to traditional methods resulting in purified fly ash being subsequently incorporated into cement. In a recent study, the researchers discovered that a batch of concrete became significantly stronger and more elastic when 30% of the cement was replaced with purified coal fly ash.
