The circular economy concept (CE) makes a salient contribution towards resource efficiency through product-life extension, redistribution/reuse, remanufacturing, and recycling as well as re-engineering of organizational processes. The construction industry is renowned for its influence on the attainment of society’s sustainable development (SD) aspirations. As such, there is a need for the industry to embrace CE principles. Yet, the uptake of these principles has not been widely reported in the context of developing economies where greenfield construction activities are burgeoning. This observation gives rise to this study. This article reports on the findings of an investigation into the utility of industrial wastes in the production of marginal construction material. To achieve this objective, a thorough geotechnical evaluation of a selection of readily available industrial wastes such as dolomitic waste (DW), silica fume (SF), and river sand (RS) deployed in different ratios according to the mass percentage of the fly ash (FA) waste to produce FA bricks was conducted. Findings suggest that the utilization of these industrial wastes in the production of FA bricks did not only portray some outstanding characteristics but also showed potential to make salient contributions to society’s sustainable aspirations. Keywords : Bricks, circular economy, dolomitic waste, fly ash, South Africa

将工业废物转化为边际建筑材料

循环经济概念（CE）通过延长产品寿命，重新分配/重用，再制造，再利用以及组织流程的重新设计对资源效率做出了显着贡献。建筑业以其对实现社会可持续发展（SD）愿望的影响而闻名。因此，该行业需要采用CE原则。然而，在新建工程蓬勃发展的发展中经济体中，尚未广泛报道采用这些原则。这一观察结果引起了这项研究。本文报告了调查工业废料在生产边际建筑材料中的效用的调查结果。为了达到这个目的，全面的岩土工程评估，根据飞灰（FA）的质量百分比，以不同的比例选择了各种容易获得的工业废物，如白云石废物（DW），硅粉（SF）和河沙（RS）。进行了FA砖的生产。研究结果表明，在FA砖生产中利用这些工业废物不仅表现出一些突出的特征，而且还显示出为社会的可持续愿望做出重要贡献的潜力。关键字：砖块，循环经济，白云石废料，粉煤灰，南非 研究结果表明，在FA砖生产中利用这些工业废物不仅表现出一些突出的特征，而且还显示出为社会的可持续愿望做出重要贡献的潜力。关键字：砖块，循环经济，白云石废料，粉煤灰，南非 研究结果表明，在FA砖生产中利用这些工业废物不仅表现出一些突出的特征，而且还显示出为社会的可持续愿望做出重要贡献的潜力。关键字：砖块，循环经济，白云石废料，粉煤灰，南非
