A Study on the Fundamental Quality of Magnesia-Phosphate-Formed Mortar Composites Using Superabsorbent Polymer for Development of Concrete for Biological Panel

Abstract

The purpose of this study was to investigate the base material of the biological panel as one of the researches for developing the biological panel using (micro)organisms. In order to select the base material for the biological panel, the applicability of the magnesia-potassium-phosphate-foamed mortar composites material using the superabsorbent polymer was evaluated through the evaluation of basic quality and characteristics. Experiments were conducted to evaluate the fluidity, compressive strength, pH, roughness (porosity distribution), and moisture retention (absorbency) of the magnesia-phosphate-foamed mortar composites according to the additional amount of the superabsorbent polymer. Experimental results showed that the addition of a suitable superabsorbent polymer can provide good results in terms of compressive strength, workability, and moisturizing properties (absorbency). As a result, it can be used as a basic quality study data of the biological panel design.
