Abstract

To investigate the impact of internal curing using superabsorbent polymers (SAPs) on the interlayer bonding properties of 3D printed mortar, this study examined the interlayer bonding properties of 3D printed mortar with different types of SAPs incorporated. The experimental results demonstrated that the addition of SAPs could enhance the interlayer bond strength of 3D printed mortar to a certain extent, with the maximum split tensile strength increased by 48.78%. The study employed the layered casting tensile method, which is simple and efficient, to assess the interlayer bond strength of the printed mortar. To investigate the influence of internal curing using superabsorbent polymers (SAPs) on the interlayer bond strength of 3D printed mortar, this study examined the interlayer bond strength of 3D printed mortars with different types of SAP added. The experimental results show that the addition of SAP can enhance the interlayer bond strength of 3D printed mortar to a certain extent, with a maximum splitting tensile strength increase of 48.78%. In order to evaluate the interlayer bond strength of printed mortar, this study used the layer casting tensile method, which is simple and efficient.

超吸收聚合物对 3D 打印砂浆层间粘结性能的影响

为了研究使用超吸收聚合物（SAP）进行内部固化对 3D 打印砂浆层间粘结性能的影响，本研究考察了加入不同类型 SAP 的 3D 打印砂浆的层间粘结性能。实验结果表明，添加 SAP 可在一定程度上提高 3D 打印砂浆的层间粘结强度，最大劈裂拉伸强度提高了 48.78%。该研究采用了简单高效的分层浇注拉伸法来评估打印砂浆的层间粘结强度。为了研究使用超吸收聚合物（SAP）进行内部固化对 3D 打印砂浆层间粘结强度的影响，本研究考察了添加不同类型 SAP 的 3D 打印砂浆的层间粘结强度。实验结果表明，添加 SAP 能在一定程度上提高 3D 打印砂浆的层间粘结强度，最大劈裂拉伸强度提高了 48.78%。为了评估打印砂浆的层间粘结强度，本研究采用了层间浇注拉伸法，该方法简单高效。
