Bonding material with fresh properties and mechanical properties suitable for extrusion 3D printing

摘要

PROBLEM TO BE SOLVED: To prevent a material extruded from a nozzle from flowing in a stationary state, extend the working time of a fresh mortar, easily extrude from a nozzle, and have sufficiently high compressive strength in various applications in the construction and construction fields. To provide a bonding material having fresh properties and mechanical properties suitable for extrusion molding 3D printing, which is developed to obtain a cement-based bonding material suitable for printing molding. SOLUTION: A binding material containing a binder, a fine aggregate, a retarder, a thickener, a surfactant, and a rheology modifier. [Selection diagram] None
