Abstract

Influence 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.

摘要

本研究考察了粒度对废耐火浇注料碱激发材料力学强度的影响。对前驱体进行了化学和矿物学分析,分离为4个粒级,并用钠水玻璃进行碱激发。对碱激发材料进行了扫描电子显微镜(SEM)和X射线衍射(XRD)全面分析,以评估力学强度方面未预料到的差异。在由产生最高抗压强度的粒级制备的样品中,研究了养护温度以及养护温度下养护时间依赖性对力学强度的影响。
