Assessing the Feasibility of Using EPS Mortar as a Construction Material for Mitigating Foam Waste

Main Article Content
Abstract
Foam is a versatile material due to its advantageous properties, such as being lightweight, impact-resistant, and providing thermal insulation. However, improper disposal or management of foam waste can lead to environmental issues. This research thus explores the possibility of disposing of foam waste by dissolving it in organic solvents, transforming it into a binder. The binder is then mixed with sand at foam-to-sand ratios of 5, 7, 9, 11, 13, 15, and 17 percent foam by weight to create EPS mortar. Two types of organic solvents, acetone and dichloromethane, were used in the study. The test results show that the EPS mortar had density values ranging from 1,200 to 1,600 kilograms per cubic meter, compressive strength ranging from 40 to 120 kilograms per square centimeter, and flexural strength ranging from 10 to 65 kilograms per square centimeter. The mortar made with acetone as the organic solvent, at a 13 percent foam ratio by weight, demonstrated the optimal balance of properties and production cost. Therefore, the EPS mortar developed in this research has potential for use in various construction applications.
