Abstract

ABSTRACTIn 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.KEYWORDS: Alkali-activated slagfibre reinforcementhot-press mouldingmechanical propertiesporositybulk density Disclosure statementNo potential conflict of interest was reported by the author(s).

不同纤维对热压成型碱活性渣(HP-FRAASC)复合材料力学和物理性能的影响

摘要在本研究中，我们将首次将热压成型方法应用于碱活性渣复合材料(AASC)的制备，并掺入1vol。- %, 3卷。- % 5卷。-%， 7vol。为了研究HP-AASC和纤维增强(HP-FRAASC)在抗压强度、抗弯强度、冲击韧性和体积密度方面的特性，HP-AASC和HP-FRAASC在基体中加入了%的钢、铜和碳纤维。结果表明，当钢纤维含量为5 vol.-%，铜纤维含量为7 vol.-%，碳纤维含量为1 ~ 3 vol.-%时，复合材料具有良好的抗弯强度、抗压强度和冲击韧性。从HP-FRAASC和HP-AASC样品中观察到，HP-AASC样品孔隙率低，密度好，制备工艺简单，可以作为该材料的合适制备方法。关键词:碱活性矿渣纤维增强热压成型力学性能孔隙度容重披露声明作者未报告潜在利益冲突。
