Experimental Analysis of MOC Composite with a Waste-Expanded Polypropylene-Based Aggregate.

Area of Science:

• Materials Science
• Civil Engineering
• Sustainable Construction

Background:

• Polypropylene (PP) is a prevalent plastic with limited recycling options.
• Expanded polypropylene (EPP) waste presents a disposal challenge.
• Magnesium oxychloride cement (MOC) offers excellent aggregate bonding properties for construction materials.

Purpose of the Study:

• To investigate the feasibility of utilizing expanded polypropylene (EPP) waste as a full aggregate replacement in magnesium oxychloride cement (MOC) composites.
• To evaluate the physical, mechanical, thermal, and water resistance properties of the developed EPP-MOC composite.
• To assess the potential of this composite as a sustainable building material.

Main Methods:

• Preparation of an air-cured MOC composite incorporating EPP waste as aggregate.
• Comprehensive testing of the composite's physical, mechanical, thermal insulation, and water resistance characteristics.
• Comparative analysis against traditional construction materials.

Main Results:

• The incorporation of EPP waste significantly enhanced the thermal insulation properties of the MOC composite.
• Mechanical resistance was reduced but remained within acceptable limits for construction applications.
• The developed composite demonstrated potential as an alternative thermal insulation material.

Conclusions:

• EPP waste can be effectively utilized in MOC composites for the building industry.
• The developed EPP-MOC composite serves as a viable alternative thermal insulation material.
• This approach contributes to plastic waste valorization and sustainable construction practices.
