摘要

摘要:本实验研究探讨了在混凝土中掺入沸石粉部分替代细骨料以及硅灰和腰果壳灰(CNSA)部分替代水泥的影响。沸石是一种天然铝硅酸盐矿物,因其具有可提高混凝土机械性能和耐久性能的沸石特性而闻名。硅灰是硅和硅铁合金生产的副产品,因其二氧化硅含量高、细度好而闻名,有助于提高混凝土的强度和密度。腰果壳灰是一种农业废料,可作为传统胶凝材料的可持续替代品,从而减少混凝土生产对环境的影响。这项实验研究调查了用沸石粉(5%、10% 和 15%)部分替代细骨料,用硅灰(3%、6%、9%、12% 和 15%)和腰果壳灰(5%、7.5%、10%、12.5%、15% 和 17.5%)替代水泥对混凝土性能的影响。这项研究强调了在可持续混凝土生产中使用沸石粉、硅灰和腰果壳灰的可行性,有助于开发更环保的建筑材料。建议进一步开展研究,探索这些替代材料在混凝土应用中的长期性能和环境效益。

Experimental Investigation on Concrete with Zeolite Powder, Silica Fume and Cashew Nut Shell Ash
Abstract: This experimental investigation explores the impact of incorporating zeolite powder as a partial replacement for fine aggregate, along with silica fume and cashew nut shell ash (CNSA) as partial replacements for cement in concrete. Zeolite, a natural aluminosilicate mineral, is known for its pozzolanic properties, which can enhance the mechanical and durability characteristics of concrete. Silica fume, a byproduct of silicon and ferrosilicon alloy production, is renowned for its high silica content and fineness, contributing to the strength and density of concrete. Cashew nut shell ash, an agricultural waste product, offers a sustainable alternative to traditional cementitious materials, potentially reducing the environmental footprint of concrete production. This experimental study investigated the effects of partially replacing fine aggregate with zeolite powder (5%,10% and 15%) and cement with silica fume (3%,6%,9%,12% and 15%) and cashew nut shell ash (5%,7.5%,10%,12.5%,15% and 17.5%) on the properties of concrete. This study underscores the viability of using zeolite powder, silica fume, and CNSA in sustainable concrete production, contributing to the development of more environmentally friendly construction materials. Further research is recommended to explore the long-term performance and environmental benefits of these alternative materials in concrete applications.
