    The effect of plasticizers on rheological, physical and mechanical properties of low cement high alumina gunning refractories by Mohammad Mobasheri, Ali Mohammad Hadian, Yasaman Mohammadi, Behzad Azimi, Mehrnoosh Kamali

    Published 2025-01-01
    “…In order to evaluate the desired properties, first the rheological properties of the samples were examined, and then for further investigations, loss on ignition (LOI), percentage of permanent linear changes (PLC), apparent porosity (AP), bulk density (BD) and cold crushing strength (CCS) tests were used. In addition, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffractometry (XRD) were used to characterize the samples. 1 and 2 wt% of CMC, H19, bentonite and ballclay were added to the mixtures as plasticizers. …”
