| summary |
This paper presents a computational method for designing architectural elements using functionally graded (FG) cementitious materials to reduce embodied carbon and mass. Functionally graded materials (FGM), commonly found in nature, have a graded variation in their composition or properties, which can be tailored to specific structural requirements. The research utilizes three grades CharCrete (biochar-cementitious mortar) developed by the author as part of more extensive research on the applications of biochar, a type of carbon-sequestering material derived from biomass. Finite element method (FEM) is used to optimize the distribution of three grades according to structural requirements. By maximizing the quantity of biochar in the CharCrete mate- rial system, the method aims to minimize embodied carbon and mass while maintaining structural integrity. The method is implemented using FEM within the Grasshopper envi- ronment with the Karamba3D plug-in and demonstrated through a design case study on load-bearing walls, comparing homogeneous and FG material allocation. The results indicate that the proposed computational method effectively guides achieving a net-negative carbon footprint, while ensuring structural performance, and suggests that a heterogeneous material allocation with two grades of CharCrete is a sufficient carbon offsetting strategy. This approach showcases a promising pathway for the architectural industry to contribute to sustainable construction practices and mitigate environmental impact through the implementation of functionally graded cementitious materials. |
