Flammability, corrosion resistance and environment by V Mhlawakhe.pdf
Laboratory work turning high ash coal fines into moulded building composites, comparing coal tar pitch against a silicone binder, with strength, burning, corrosion and leaching tests. For product developers.
Air blowing converted coal tar into a pitch with 11.27% volatile matter and 87.68% fixed carbon, which bound high ash coal fines into structural composites. Compressive strengths ran from 106.58 to 344.71 MPa and flexural strengths from 48.75 to 159.30 MPa. Flammability was low across all composites and corrosion rates stayed below those of some commercial ceramic tiles.
