Description

This study assesses the moisture transport phenomena of 3D printing lime-cement mortars with Phase Change Materials (PCM) and Cellulose Fibers (F) for architectural applications comparing experimental results and numerical analyses. A lime-cement control mortar was designed and cellulose fibers and different percentages of PCM (i.e., 10, 20 and 30%) were added, leading to a total of eight different mixtures. Physical and mechanical characterization tests were performed on mortar samples and capillary water absorption tests were carried out over 24h. Based on the experimental results, a computational nonlinear FE-based Moisture Diffusion model was calibrated to simulate the data.
