Nano-Pozzolanic Reaction Empowering Sustainable Construction with Hydrogel

초록

In the pursuit of enhancing the environmental sustainability of concrete, a fundamental construction material, traditional approaches often emphasize minimizing maintenance requirements to extend lifespan and improve durability. Departing from these conventional strategies, an innovative method aimed at augmenting thermal insulation and eco-friendliness of building structures is proposed, which involves the integration of nanoclay (NC) hydrogel to confer multifunctionality upon cement materials. Within the hydrogel matrix, NC functions as an internal cross-linking agent, establishing robust bonds with cement through a surface pozzolanic reaction. Rigorous validation of this interaction is conducted through meticulous adhesion measurements, assessments of changes in bonding energy, and simulations of shear forces. Significantly, the bonded NC hydrogel, enriched with water, demonstrates a remarkable ability to supply essential moisture for the successful settlement and growth of aquatic organisms and moss. This comprehensive study underscores the potential of NC hydrogel as an invaluable material for establishing the foundations of thriving ecosystems, presenting a promising avenue for sustainable construction practices.
