Mechanical properties of recycled Glass Fiber Reinforced Polymers (rGFRP) in limestone calcined clay cement mortars.

Glass fiber-reinforced polymer (GFRP) composite materials are used extensively and increasingly in major industries including aerospace, marine, construction, electrical and automotive. These types of materials have advantages such as low densities, high mechanical properties in certain directions, ease of production and durability. However, its manufacture generates residues and at the end of its life cycle both the fiber and the resin cannot be easily decomposed or recycled. This article explored the influence of recycled GFRPs as reinforcement in limestone calcined clay cements mortar mixes with ratios of 2%,4%,6%, 8% and 10% replacing the fine aggregate weight in the flexural strength, compressive strength, and density. Results demonstrated flexural and compressive strengths in the range of 2.5 MPa-7MPa and 12-28 MPa respectively at the ages of 28 and 56 days. [ABSTRACT FROM AUTHOR]
