In the context of ecological sustainability, this study focuses on the effect of variables of pasture fibers on the thermal properties of slag bricks made from a green recyclable material. This experiment uses slag as the binder, sand as the aggregate, and pasture fiber as an additive. The experimental variables include the additive content ratio of the pasture fiber, the size of the pasture fiber, and the type of pasture fiber. Significance analysis of the experimental results of the thermal performance tests is carried out using Minitab 18.1.0 software, and the optimal ratios for the thermal performance of the composite samples are derived from the response optimizer and conformity analysis. The results of the experiment's test analysis using Minitab 18 software indicate that, with an increase in pasture fiber content, the thermal performance of the composite samples initially decreases before increasing. Additionally, the lower the thermal conductivity of the composite sample, the lower the apparent density and the higher the porosity. Incorporating pasture fibers into slag bricks, as revealed in this study, reduces the waste of pasture resources in pastoral areas and promotes the development of sustainable building materials with favorable thermal properties.
在生态可持续发展的背景下，本研究聚焦于牧草纤维变量对由绿色可回收材料制成的矿渣砖热性能的影响。本实验以矿渣为粘结剂，砂为集料，并使用牧草纤维作为添加剂。实验变量包括牧草纤维的添加剂含量比、牧草纤维的尺寸以及牧草纤维的类型。使用Minitab 18.1.0软件对热性能测试的实验结果进行显著性分析，并通过响应优化器和一致性分析得出复合样品热性能的最佳比例。使用Minitab 18软件进行实验测试分析的结果表明，随着牧草纤维含量的增加，复合样品的热性能先降低后升高。此外，复合样品的导热系数越低，其表观密度越低，孔隙率越高。本研究表明，将牧草纤维掺入矿渣砖中，减少了牧区牧草资源的浪费，并促进了具有良好热性能的可持续建筑材料的发展。
