초록

With a melting point at 30℃ and adhesive strength of 4.12MPa, the nontoxic and eco-friendly biopolymer gelatin finds frequent use in the food, pharmaceutical, and medical industries. Previous studies introduced gelatin as a component in the innovative concept of Living Building Material (LBM), but insufficient attention was given to porosity. This study explores the relationship between porosity and the compressive strength of gelatin-sand composite, aiming to understand how void space influences overall strength. Porosity was calculated by measuring the density of the entire specimen. The compressive strength increased by 18% as porosity decreased by 15% from the 7th day to the 14th day. Additionally, the adhesive strength of gelatin solution exhibited a 3.11 times increase from the first to the fourteenth day, similar to cement mortar. The compressive strength in the sand-gelatin composite improved by 18% due to the enhanced gelatin adhesive strength. Furthermore, SEM image analysis was conducted to observe the morphology of the sand-gelatin composite.
