A basic study of Properties of Cement Mortar for 3D Printing Concrete Using Methyl Cellulose Thickener

메틸셀룰로오스(MC)계 증점제 혼입에 따른 3D 프린팅 콘크리트용 시멘트계 모르타르의 특성 변화에 대한 기초적 연구

Integrating 3D printing into architecture is gaining attention because it allows construction of construction structures without formwork. Among them, 3D printing construction materials must have high flow performance and at the same time ensure the performance that does not collapse during lamination. Therefore, in this study, we tried to determine the fluidity and lamination properties of mortar formulations, and set the thickener incorporation ratio as the formulation parameters. As a result of this experiment, it was confirmed that the lamination performance was secured from the thickening agent mixing rate of 1.5%.
