ABSTRACT An experimental study focused on the determination of mechanical properties of synthetic green sand system using Nagavali river sand by adding banana peel powder as an additive. Compression strength, shear strength, mould hardness bulk density and permeability are the various properties found in the laboratory following standard testing procedures. Sand aggregate is prepared by mixing the bentonite as binder and banana peel powder as an additive to the silica sand in various amounts. Encouraging results in terms of strength and hardness are obtained by testing the standard sand samples. In fact, the properties exhibited are almost similar to the values obtained by addition of 2% dextrin as an additive to the sand aggregate. Since the banana peel powder can be easily prepared which is most economical in terms of cost compared with dextrin, that can be an alternative additive in preparing the sand moulds to obtain adequate strength and hardness.

香蕉皮粉作为合成湿型砂造型系统替代添加剂的适用性研究

摘要 一项实验研究的重点是通过添加香蕉皮粉作为添加剂，使用 Nagavali 河沙测定合成湿砂系统的力学性能。压缩强度、剪切强度、模具硬度堆积密度和渗透性是实验室按照标准测试程序发现的各种特性。砂骨料是通过将膨润土作为粘合剂和香蕉皮粉作为添加剂以不同量混合到硅砂中制备的。通过测试标准砂样，在强度和硬度方面获得了令人鼓舞的结果。事实上，所表现出的特性几乎与通过向砂骨料中添加 2% 糊精作为添加剂获得的值相似。由于香蕉皮粉易于制备，与糊精相比，在成本方面最为经济，
