Abstract
ABSTRACT In this study, we will apply the hot-press moulding method for the first time to the preparation of alkali-activated slag composites (AASC) and incorporate 1vol.-%, 3vol.-%, 5vol.-%, and 7vol.-% steel, copper, and carbon fibres into the matrix in order to investigate the characteristics of the HP-AASC and fibre reinforced (HP-FRAASC) in terms of compressive strength, flexural strength, impact toughness, and bulk density of HP-AASC and HP-FRAASC. Results show that the composites have good flexural strength, compressive strength, and impact toughness when the content of steel fibres is 5 vol.-%, copper fibres are 7 vol.-%, and carbon fibres are 1–3 vol.-%. It was observed from each sample of HP-FRAASC and HP-AASC that the HP-AASC samples had lower porosity, better density, and an easy preparation process, which can be used as a suitable preparation method for this material.
