Study of new reinforcing materials for cementitious panel production

Area of Science:

• Materials Science
• Civil Engineering
• Sustainable Construction

Background:

• Growing demand for sustainable building materials.
• Need to reduce production costs and improve material properties.
• Exploration of novel raw materials for cement-based products.

Purpose of the Study:

• Evaluate the impact of various reinforcement materials on cement panels.
• Assess physical-mechanical and thermal properties of reinforced cement panels.
• Compare performance of pine wood, coffee husk, rice husk, and PET reinforcements.

Main Methods:

• Production of cement-based panels with specified ratios of reinforcement materials, cement, water, and additives (Portland ARI V cement, calcium chloride).
• Testing of physical, mechanical, and thermal properties before and after accelerated aging.
• Comparative analysis of panel performance based on reinforcement type.

Main Results:

• Cement panels reinforced with polyethylene terephthalate (PET) waste exhibited the best physical and mechanical performance, surpassing pine wood reinforcements.
• Panels using coffee husk and rice husk waste showed lower physical-mechanical performance but demonstrated the lowest thermal conductivity.
• Accelerated aging tests were conducted to assess durability.

Conclusions:

• PET bottle waste shows significant potential as a reinforcement material for high-performance cement-based panels.
• Coffee husk and rice husk waste offer potential for applications requiring low thermal conductivity, despite limitations in physical-mechanical properties.
• The study highlights the viability of incorporating diverse recycled materials into building components.
