Influence of particle size on compressive strength of alkali activated refractory materialsHorvat, Barbara (Avtor) Ducman, Vilma (Avtor) refractory materialsalkali activationparticle sizeSEMXRFXRDcompressive strengthInfluence of particle size on the mechanical strength of alkali activated material from waste refractory monolithic was investigated in this study. Precursor was chemically and mineralogically analysed, separated on 4 fractions and alkali activated with Na-water glass. Alkali activated materials were thoroughly investigated under SEM and XRD to evaluate the not predicted differences in mechanical strength. Influence of curing temperature and time dependence at curing temperatures on mechanical strength were investigated in the sample prepared from a fraction that caused the highest compressive strength.Molecular Diversity Preservation International20202023-08-21 14:55:51Neznano16809UDK: 620.1/2ISSN pri članku: 1996-1944DOI: 10.3390/ma13102227COBISS_ID: 15054083sl© 2020 by the authors.
