NOVELTY - A magnesium phosphate cement-based material comprises composite thixotropic agent comprising magnesium sulfate and diatomaceous earth. USE - Magnesium phosphate cement-based material for three-dimensional printing and building construction (all claimed). ADVANTAGE - The magnesium phosphate cement-based material provides three-dimensional printed product with reduced deformation rate and increased number of three-dimensional printed structure layers and height, and effectively improves structural recovery ability of material during construction stage after extrusion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the magnesium phosphate cement-based material.
