This study was conducted on composite materials consist of construction waste, bentonite, and lime for landfill liner. In this case, Matlab version 2019a was used to analyze composite variables for desiccation crack. In the mixture of construction waste, bentonite, and lime, there is a desiccating behavior. This study found that the addition ≤ of 20% bentonite could cause more significant cracks. The addition of 1% lime can reduce the level of soil shrinkage so that cracks are less than with the addition of bentonite. The results have four variations of composites that meet the soil shrinkage limit ≤ of 4 % not to cause significant cracks.
