- Abstract
As one of the element technologies for the realization of Vertical Greenery System (VGS), this study aims to develop a biological panel in which moss can thrive. The fundamental characteristics and the biological receptivity of the base material of the biological panel should be considered for moss survival. Therefore, the required performance of the base material of the biological panel has been evaluated, and the effect on biological receptivity has been analyzed. For biological receptivity, it is necessary to create an environment having various pH ranges depending on the species of moss, secure the rooting performance of moss, and secure the moisturizing properties of the base material of the biological panel. Therefore, in this study, two types of cement with different pH (Ordinary Portland Cement and Alumina Cement) have been used to enhance the fundamental characteristics and the biological receptivity of the base material of the biological panel. Additionally, a foaming agent (aluminum powder) has been incorporated to reduce the panel's weight and create a rough surface. Super absorbent polymer has been incorporated to improve the moisture-retention properties of the biological panel's base material. As a result of the presented evaluation, panels with pH values of 13 and 10.5 have been prepared, and the moisture absorption has been increased by 25% through the use of Super Absorbent Polymer (SAP), with moisture being maintained for about 2-3 days.
