This study investigates the mechanical strength, durability, and microstructural properties of organic lime plasters applied to brickwork walls, emphasizing their performance in both fresh and hardened states. Two mix ratios, 1:2 and 1:3 (lime to sand), were evaluated. Experimental methods included compressive and flexural strength testing, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX), porosity measurements, acid resistance tests, and water absorption analysis. The 1:2 mix ratio exhibited a compressive strength of 4.01 N/mm2 at 84 days, indicating enhanced mechanical performance compared to the 1:3 mix. Results demonstrated that organic lime mortars improved bonding characteristics and durability, making them a viable, sustainable alternative to conventional plasters. Understanding the interaction between organic lime plasters and brick substrates is essential for optimizing performance in eco-friendly masonry applications.

摘要

This study investigates the mechanical strength, durability, and microstructural properties of organic lime plasters applied to brickwork walls, emphasizing their performance in both fresh and hardened states. Two mix ratios, 1:2 and 1:3 (lime to sand), were evaluated. Experimental methods included compressive and flexural strength testing, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX), porosity measurements, acid resistance tests, and water absorption analysis. The 1:2 mix ratio exhibited a compressive strength of 4.01 N/mm2 at 84 days, indicating enhanced mechanical performance compared to the 1:3 mix. Results demonstrated that organic lime mortars improved bonding characteristics and durability, making them a viable, sustainable alternative to conventional plasters. Understanding the interaction between organic lime plasters and brick substrates is essential for optimizing performance in eco-friendly masonry applications.
