Resources natural are limited and run out over time. The building construction sector uses a large number of nature reserves. In previous years, several researchers have attempted to formulate an environmentally friendly mortar from waste materials such as fly ash. In this study, an ecological mortar was developed by replacing some of the cement with fly ash. Various tests were performed to determine the mechanical properties of normal mortar and fly ash (FA) mortars. In this current research, the study was conducted in three different stages. In Phase I, An eco-friendly mortar was manufactured by replacing part of the cement with fly ash powder and replacing tap water (TW) with magnetised water (MW). In Phase II, the Taguchi method and JMP Trial 15 software were used to optimise the design of the mixture. In Phase III, samples of the optimised mixture were cast for testing to confirm the resistance to bending. In addition, the study was extended to analyse the microstructural properties of mortars characterised by SEM. Itwas concluded a 10% replacement of a part of the cement by fly ash powder and replacement of (TW) by (MW) was found to be optimal and can be used appropriately for green mortar design.

粉煤灰估值:基于磁化水的生态砂浆在建筑材料中的应用新视野

自然资源是有限的,会随着时间的推移而耗尽。建筑施工部门使用了大量的自然保护区。前几年,一些研究人员试图用粉煤灰等废料配制环保砂浆。在这项研究中,通过用粉煤灰代替一些水泥开发了一种生态砂浆。进行了各种测试以确定普通砂浆和粉煤灰 (FA) 砂浆的机械性能。在目前的研究中,该研究分三个不同的阶段进行。在第一阶段,通过用粉煤灰粉代替部分水泥和用磁化水(MW)代替自来水(TW)来制造环保砂浆。在第二阶段,使用田口方法和 JMP Trial 15 软件来优化混合物的设计。在第三阶段,浇铸优化混合物的样品用于测试以确认抗弯曲性。此外,该研究还扩展到分析由扫描电镜表征的砂浆的微观结构特性。结论是用粉煤灰粉代替 10% 的水泥,用 (MW) 代替 (TW) 被认为是最佳的,可以适当地用于绿色砂浆设计。
