Desenvolvimento de um compósito de gesso e resíduos de poda de árvores aditivado com baba de cupim sintética para produção de pré-moldados.

Abstract

In conventional construction, the traditional method uses masonry and requires on-site preparation of mortar for laying, generating waste that leads to economic and environmental impacts, delays in project execution, material waste, and imprecision, thus affecting the sustainability of construction. Projects that employ drywall construction technology present a lower structural weight, shorter execution time, and lower costs compared to masonry structures. This research develops an innovative composite for precast panels, combining beta gypsum, tree pruning residues, and a synthesized substance similar to "termite saliva." The objective is to create a sustainable material with improved mechanical strength and moisture resistance. Second-order polynomial regression models confirmed the predictive quality of the adjustments, with coefficients of determination (R²) ranging from 77.55% to 83.05%, with the compressive strength model being the most robust. These results validate the adopted approach and provide a solid foundation for future refinements in the development of composites for precast applications.
