Blended cements definition

Part 3 Classes of Materials starts with the selective treatment of metals that are applied as base and alloying elements of metallic materials. The next class of materials discussed are ceramics. Detailed groupings and definitions of technical ceramics are given and traditional ceramics and cements, silicate ceramics, refractory ceramics, oxide ceramics, and nonoxide ceramics are treated. The physical and physicochemical properties of those polymers, copolymers, and polymer blends which are widely used for scientific applications and in industry are described in the next chapter. The last chapter serves as a source of data and commercial product information on glasses as engineering materials of practical importance. 

According to RCRA, oil-containing sludge from storage tanks and refinery water treatment facilities is by definition hazardous, and should be sent to a hazardous land fill. In most cases, a lot of the sludge can be dissolved with detergents and/or or solvents (such as hot diesel oil) and blended into cmde oil. Alternatively, dissolved sludge can go to delayed cokers, asphalt plants, carbon black plants, or cement kilns. 

Research in new SCMs and portland cement-SCM blends is increasing significantly and it is expected to further increase in the next decades, considering the global challenges that the cement industry faces for development of more sustainable concrete. The SCMs with the highest potential are all less-crystalline or amorphous phases and NMR spectroscopy will definitely play an important role in the exploration of these new SCMs and their reactivity in cementitious systems.
