Abstract

In this research, the performance of fly ash/GGBS geopolymer mortars made with different quarry waste powder as filler materials by substituted the river sand fine aggregate with different ratios was evaluated based on the mechanical, physical, durability properties and microstructural analysis. Limestone waste, marble waste and basalt waste powder were used as filler materials developing eco-friendly and economical geopolymer from industrial waste as a promising sustainable area of research. A series of tests were conducted such as on strength properties, ultrasonic pulse velocity (UPV), physical properties, abrasion resistance test, splitting tensile strength and microstructure analysis (SEM). The samples were elevated at the high-temperatures of 200 °C, 400 °C, 600 °C and 800 °C. Results conducted that the use of limestone waste powder and marble waste powder up to 50% ratio improved the geopolymer composite's strength. The three filler geopolymer composites positively affected water absorption, strength properties and abrasion ratio results. The current article’s finding has indicated a potential solution, presenting another geopolymer class followed by the successful use of fly ash and quarry waste as significant asset materials. The output of this study is commercially expected to be effective intercession for waste recycled and friendly environmental management conclusions.

摘要

本研究基于力学性能、物理性能、耐久性能和微观结构分析，评价了以不同采石场废弃粉末为填充材料，替代不同配比的河砂细骨料制备的粉煤灰/GGBS地质聚合物砂浆的性能。石灰石废料、大理石废料和玄武岩废料粉末被用作填充材料，从工业废料中开发环保且经济的地质聚合物，这是一个很有前景的可持续研究领域。进行了强度性能、超声脉冲速度（UPV）、物理性能、耐磨性测试、劈裂拉伸强度和显微组织分析（SEM）等一系列测试。样品在 200°C、400°C、600°C 和 800°C 的高温下升高。结果表明，石灰石废粉和大理石废粉的使用比例高达50%，提高了地质聚合物复合材料的强度。三种填料地质聚合物复合材料对吸水性、强度性能和磨损比结果有积极影响。当前文章的发现表明了一种潜在的解决方案，提出了另一种地质聚合物类别，然后成功使用飞灰和采石场废料作为重要的资产材料。本研究的输出预计将在商业上有效地为废物回收和友好的环境管理结论代祷。当前文章的发现表明了一种潜在的解决方案，提出了另一种地质聚合物类别，然后成功使用飞灰和采石场废料作为重要的资产材料。本研究的输出预计将在商业上有效地为废物回收和友好的环境管理结论代祷。当前文章的发现表明了一种潜在的解决方案，提出了另一种地质聚合物类别，然后成功使用飞灰和采石场废料作为重要的资产材料。本研究的输出预计将在商业上有效地为废物回收和友好的环境管理结论代祷。
