Raws li qhov tseeb tias bauxite clinker muaj cov thermal conductivity me me thiab zoo dua skid tsis kam thiab hnav-tiv taus cov cuab yeej, nws tuaj yeem siv rau hauv HFST (kev sib txhuam siab saum npoo kho) lossis cov txheej txheej ntawm asphalt sib tov los hloov lossis ib nrab hloov cov aggregate uas twb muaj lawm. Bauxite clinker tau muab faib ua feem ntau rau hom raws li cov ntsiab lus sib txawv ntawm cov tshuaj lom neeg. Kev xaiv ntawm bauxite clinker li aggregate tsis yog tsuas yog rau kev lag luam tus nqi, tab sis kuj rau kev txhim kho cov adhesion ntawm aggregate thiab asphalt, uas muaj ib qho kev dig muag.Qhov kev tshawb fawb no tau soj ntsuam cov yam ntxwv ntawm ntau hom bauxite clinker.Qhov adhesion ntawm ntau hom. bauxite clinker nrog asphalt tau soj ntsuam los ntawm txoj kev agitating hydrostatic adsorption txoj kev thiab nto dawb zog txoj kev xav.Cov nyhuv ntawm cov yam ntxwv tsis ntawm bauxite clinker ntawm adhesion tau soj ntsuam los ntawm grey correlation entropy tsom xam.
Bauxite yog lub ntuj, tawv heev thiab yog feem ntau muaj cov txhuas oxide compounds (alumina), silica, hlau oxides thiab titanium dioxide. Kwv yees li ntawm 70 feem pua ntawm lub ntiaj teb bauxite ntau lawm yog refined los ntawm bayer chemical txheej txheem rau hauv alumina.
Bauxite yog cov khoom siv zoo tshaj plaws rau kev tsim cov alumina. Ib cag ntawm cov ntsiab lus tseem ceeb ntawm txhuas thiab silicon, bauxite feem ntau ua ke nrog ntau yam tseem ceeb xws li gallium (Ga), titanium (Ti), scandium (Sc), thiab lithium (Li). Kev tsim khoom feem ntau suav nrog cov khoom tseem ceeb ntawm cov khoom tseem ceeb, ua rau lawv muaj peev xwm ntawm polymetallic. Kev rov qab los ntawm cov khoom tseem ceeb no tuaj yeem ua rau muaj txiaj ntsig zoo ntawm alumina manufacturing process efficiency thaum txo cov kev lav phib xaub thiab kev cuam tshuam ib puag ncig. Txoj kev tshawb no muab kev soj ntsuam tseem ceeb ntawm cov cuab yeej siv tam sim no siv los rov qab cov khoom muaj txiaj ntsig los ntawm bauxite residue thiab siv cov cawv siv los muab kev pom rau kev siv dav dav ntawm bauxite residue raws li cov peev txheej es tsis yog pov tseg. Kev sib piv ntawm cov txheej txheem uas twb muaj lawm qhia tau hais tias ib qho kev sib koom ua ke rau cov khoom muaj txiaj ntsig zoo rov qab thiab txo cov pov tseg pov tseg yog qhov zoo.
