Abstract

Utilizing local materials and recycling waste has the potential to yield both ecological and economic advantages in the field of construction materials. In this context, the object of this work is to apply Taguchi's design of experiments on cement eco-mortar, which were designed using an L-9 orthogonal array, to optimize and model the effect of dune sand of the El Oued region, rubber aggregates, and crushed clay brick waste on the mechanical strength at 28 days. The different interactions were also investigated between the factors targeted in our study, namely: dune sand (DS) content, rubber aggregates (RA) content, and brick waste (BW) content. The results of the analysis of variation (ANOVA) as well as the mathematical models developed in this study showed that the BW factor content has a positive effect on compressive strength and a negative effect on flexural strength. In addition, the interactions between DS and BW contents and between RA and BW contents have a negative effect on the compressive strength of eco-mortar. With regard to flexural strength, the results showed that the interaction between the factors DS and RA contents has a negative effect on flexural strength, in contrast to the interaction between the RA and BW contents, which has a positive effect.

用田口方法优化沙丘砂、再生橡胶骨料和粘土砖废料对生态砂浆机械强度的影响

在建筑材料领域，利用当地材料和回收废物有可能产生生态和经济优势。在此背景下，本研究采用田口试验设计法对水泥生态砂浆进行试验，试验设计采用 L-9 正交阵列，以优化和模拟埃尔韦德地区沙丘砂、橡胶骨料和碎粘土砖废料对 28 天机械强度的影响。我们还研究了沙丘砂（DS）含量、橡胶集料（RA）含量和砖块废料（BW）含量这几个目标因素之间的相互作用。变异分析（ANOVA）和本研究建立的数学模型的结果表明，BW 因子含量对抗压强度有正向影响，而对抗折强度有负向影响。此外，DS 和 BW 含量之间以及 RA 和 BW 含量之间的交互作用对生态砂浆的抗压强度有负面影响。在抗折强度方面，结果表明 DS 和 RA 含量之间的交互作用对抗折强度有负面影响，而 RA 和 BW 含量之间的交互作用则有正面影响。

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
