摘要

摘要:通过实验研究了废玻璃粉(WGP)作为细骨料在焚烧生物医疗废弃物灰(IBWA) -磨粒高炉渣(GGBFS)基地聚合物混凝土(GPC)中的结构和材料性能。研究了以IBWA为粘结剂，WGP为细骨料的ggbs基地聚合物混凝土的抗压、劈裂、拉伸和弯曲效率。为了确定混凝土的强度，设计了四种不同比例的梁和柱。计算了梁的抗压强度和劈裂抗拉强度等力学性能和挠曲性能，如挠度、延性系数、挠曲强度和韧性指数，以及柱的挠曲性能，如承载能力、应力-应变行为和荷载-挠曲行为。对比分析了废玻璃粉和焚烧生物医学废灰在ggbs基地聚合物混凝土中对钢筋水泥混凝土(RCC)的性能。研究结果表明，废玻璃粉和焚烧后的生物医疗废弃物灰分在ggbs基地聚合物混凝土中表现出最高的断裂能，这与废料与ggbs基地聚合物混凝土之间的力学键合预测一致。

Influence of incinerated biomedical waste ash and waste glass powder on the mechanical and flexural properties of reinforced geopolymer concrete

ABSTRACT An extensive experimental study was implemented to investigate the structural and material properties of Waste Glass Powder (WGP) as fine aggregate in Incinerated Bio-Medical Waste Ash (IBWA) – Ground Granulated Blast Furnace Slag (GGBFS) based Geopolymer Concrete (GPC). The research was based on the compressive, splitting tensile and flexural efficiency of GGBS-based geopolymer concrete mixed with IBWA as binder and WGP as fine aggregate. To determine the concrete strength, four different types of proportions were designed as beams and columns. The mechanical properties such as compressive strength and splitting tensile strength and flexural properties for beams such as deflection, ductility factor, flexural strength, and toughness index, and flexural properties for columns such as load-carrying capacity, stress-strain behaviour, and load-deflection behaviours were calculated. Comparative analyzes were performed to assess the efficiency of Waste Glass Powder and Incinerated Biomedical Waste Ash in GGBS-based geopolymer concrete against Reinforced Cement Concrete (RCC). The findings showed that the Waste Glass Powder and Incinerated Bio-Medical Waste Ash embedded in GGBS-based Geopolymer concrete exhibited the highest fracture energy, as predicted from the mechanical bond between the waste materials and the GGBS-based Geopolymer concrete.

期刊介绍： The Australian Journal of Structural Engineering (AJSE) is published under the auspices of the Structural College Board of Engineers Australia. It fulfils part of the Board''s mission for Continuing Professional Development. The journal also offers a means for exchange and interaction of scientific and professional issues and technical developments. The journal is open to members and non-members of Engineers Australia. Original papers on research and development (Technical Papers) and professional matters and achievements (Professional Papers) in all areas relevant to the science, art and practice of structural engineering are considered for possible publication. All papers and technical notes are peer-reviewed. The fundamental criterion for acceptance for publication is the intellectual and professional value of the contribution. Occasionally, papers previously published in essentially the same form elsewhere may be considered for publication. In this case acknowledgement to prior publication must be included in a footnote on page one of the manuscript. These papers are peer-reviewed as new submissions. The length of acceptable contributions typically should not exceed 4,000 to 5,000 word equivalents. Longer manuscripts may be considered at the discretion of the Editor. Technical Notes typically should not exceed about 1,000 word equivalents. Discussions on a Paper or Note published in the AJSE are welcomed. Discussions must address significant matters related to the content of a Paper or Technical Note and may include supplementary and critical comments and questions regarding content.
