Ho sebetsana le tšebeliso e kholo ea liindasteri litšila carbide slag le ho lokisetsa khabone e tlaase, theko e tlaase composite phasejeng ho fetola mocheso thepa, bafuputsi ba Beijing University of Civil Engineering le Architecture sisintsweng ho sebelisa carbide slag e le lintho tse bonahalang scaffold. Ba sebelisitse mokhoa o batang oa sintering ho lokisa Na₂CO₃/carbide slag composite phase phetoho lisebelisoa tsa polokelo ea mocheso, ho latela mehato e bontšitsoeng setšoantšong. Ho ile ha lokisoa lisampole tse supileng tsa likarolo tsa phetoho tse nang le likarolo tse fapaneng (NC5-NC7).
