What is it about?
Mangrove propagules require a temporary protective structure that provides an optimal balance of strength—sufficient to shield them from wave currents without being overly rigid, which can be challenging. To address this, we propose using porous concrete pots incorporating high volumes of fly ash activated with low concentrations of NaOH. This design offers several advantages: the permeable structure allows water to pass through, reducing pressure from waves while still offering protection to the propagules. The use of fly ash as a primary material not only enhances the sustainability of the pots but also contributes to the mechanical properties needed to withstand environmental forces.

Why is it important?
Mangrove forests play a crucial role in environmental conservation. However, retransplanting mangrove propagules faces challenges, and success rates are notably low. Achieving an optimal protector for propagules, balancing strength without impeding growth, is challenging.
Perspectives
Writing this article has been a rewarding experience, particularly due to the collaboration with long-standing co-authors, which has enriched the research process. This work presents a novel approach to sequencing mixtures containing fly ash, providing new insights into optimizing its use in various applications. Additionally, the article proposes an innovative solution for protecting mangrove propagules from the impact of large waves. This proposal highlights the potential of incorporating fly ash in environmental protection strategies, particularly in coastal areas vulnerable to erosion and wave action. The findings contribute to both material science and ecological conservation efforts.
