A tremendous amount of cement solid wastes from the cement plant still considered an environmental obstacle.
The trend of co-processing widely accepted with the growing attention to the environment. On the spot and fast
chemical analyses will provide tangible support to the decision maker to allow such an earlier mentioned material
to go through co-processing and monitor the quality. In this study, modern chemical analysis methods
were employed to assist the possibility of waste material co-processing within the cement plant. Real samples
were collected from a cement plant in Egypt to validate and support the approach of co-processing. The samples
were analyzed using two advanced techniques of Laser-induced breakdown spectroscopy (LIBS) and inductively
coupled plasma optical emission spectrometry (ICP-OES). In this study, the results show that the composition of
the collected samples contains the principal elements required for clinker and cement production. However,
some heavy metals and other hazardous elements exist, but the concentration is below the accepted range of the
specifications. In the present work, the ICP has used as a confirmation tool for the laser-induced breakdown
simple analysis of cement raw materials. The results can suggest considering this approach implemented for
effective co-processing in the cement plant. The combination of using LIBS analysis followed with ICP-OES offer
very efficient approach suitable to provide enough information to decide on the cement solid waste materials to
go through co-processing. |
