Environmentally mortar development using Washingtonia/biochar waste hybrid: mechanical and thermal properties

Adopting cleaner technological solutions has become a key component of traditional building design in order to ensure the sustainability of buildings. A good substitute for aggregates in mortars in the construction industry is the valorization of agricultural material wastes. An effort to create novel materials capable of absorbing and storing carbon dioxide has been initiated in response to the planet’s warming (CO₂). A novel’s environmental, mechanical, and thermal performance, light-weight binder composed of biodegradable materials, Washingtonia filifera (WWF) waste, and biochar from WWFB combustion were compared. WWF and WWFB were used to replace a portion of the plaster at weight-based dosages of 0%, 1%, 1.5%, 2%, and 3%. In order to understand the impact additives, have on microstructural modifications and macroscopic qualities, it is important to compare the morphology and mineralogical composition of the plaster with and without additions using microstructural analysis. (SEM, TGA/DSC and FTIR). RSM has been used as ANN to optimize the variables affecting the thermal and mechanical characteristics of biocomposites as the application for insulation materials. The findings show that the thermal performance has improved by the inclusion of 2.5% WWF and 0.5% WWFB pyrolyzed at 500°C in partial replacement of cement, leading to a 49% drop in thermal conductivity compared to control mortar. The identical composition of WWF and WWFB also produced 197% and 102% increases in displacement and bending strength, respectively.
