Abstract

Soil is a very important element in the success of a development project and is part of the foundation used. Therefore, stable soil is needed to obtain the required soil bearing capacity. Such as clay has the characteristics of low bearing capacity and large shrinkage. This study aims to determine the increase in the value of the shear strength of clay with the stabilization of PET plastic waste. The purpose of this study is to see the value of the shear strength of clay with variations in the amount of plastic waste 0%, 3.5%, 4%, and 4.5%. Method used is SNI 3420:2016 for the shear strength test. As a result, the addition of shredded plastic waste can increase the value of the shear strength of the soil.The value of shear strength increased at the percentage of plastic addition of 3.5% of 0.5663 kg/cm2 in the original soil test, the value of shear strength was 0.5271 kg/cm2, an increase of 7.43%. The conclusion is that there is an increase in the value of the shear strength of the soil stabilized by plastic waste at a variation of 3.5% of plastic waste, an increase of 7.43%.

废塑料(PET)添加对粘土抗剪强度的影响试验研究

土壤是开发项目成功的一个非常重要的因素，也是所使用的基础的一部分。因此，需要稳定的土壤来获得所需的土壤承载力。如粘土具有承载力低、收缩率大的特点。本研究旨在确定PET塑料废料稳定化后粘土抗剪强度的增加值。本研究的目的是观察废塑料添加量为0%、3.5%、4%、4.5%时粘土抗剪强度的变化情况。抗剪强度试验采用SNI 3420:2016方法。由此可见，塑料垃圾碎料的加入可以提高土的抗剪强度值。原土试验中，当塑料添加量为0.5663 kg/cm2的3.5%时，抗剪强度值增加，抗剪强度值为0.5271 kg/cm2，增加7.43%。结果表明，废塑料稳定土的抗剪强度随废塑料的3.5%变化而增大，增幅为7.43%。
