A kerozint a cement fajsúlyának meghatározására használják, mert amikor kísérletezés (tesztelés) során vizet használnak, az reakcióba lép a cementtel, és kalcium-oxidot (CaO) képez. Ez befolyásolja a kísérletet, de a kerozin nem lép reakcióba a cementtel, és nincs hatással a kísérletre. WebNIST started using gas pycnometry, instead, to quantify hydraulic cement density since 2012 as it is faster, generates no chemical to dispose. Gas-comparison pycnometry has been approved since 1967 as the standard testing method following ASTM C604, “True Specific Gravity of Refractory Materials” [7].
