摘要：
To investigate the influences ofprintingtimeintervalandfiberdosageonthe interlayer bond strength of 3D printing cement-based materials, the tensile bond strength and shear bond strength were measured by a cross-bonded method. Thechangeofinterlayerbondstrength with timeinterval was analyzed. The results show that the cross-bonded method can effectively measure the tensile bond strength and shear bond strength of 3D printing cement-based materials and eliminate the disadvantage of eccentricityin direct tension test. The interlayer bond strengths before and after the final setting are different. Before the final setting, the bond strength of the 3D printing cement paste decreases with the increase of time interval. After the final setting, the tensile bond strength does not change, while the shear bond strength increases with the increase of time interval. The interlayer bond strength of 3D printing cement paste cannot be improved via adding fibers. © 2019, Editorial Department of Journal of the Chinese Ceramic Society. All right reserved.
