dc.description.abstract | The fluid catalytic cracking (FCC) catalyst waste (CW) is eroded catalyst debris from the cracking unit, which is collected by an electrostatic precipitator. CW is zeolite material, which unique properties are underused in refractory castable production technology. This work deals with untreated CW and thermally treated – CWt. The hydration and structure development of cementitous compositions with CW and CWt were investigated. In comparison with CW, CWt is a considerably softer accelerating additive of cement hydration and a certain amount of this additive (10 - 20 %) markedly increases the compressive strength of cementitious stone. The impact of CWt additive on refractory castable properties was investigated. It was established that the increase of CWt additive content causes the increase of castable’s compressive strength and decrease of shrinkage, ensures a more compact structure of castable and best thermal durability versus analogical castable without the additive. | eng |
