This paper examines the influence of dosing method and material characteristic of superabsorbent polymers (SAP) used for internal curing, on the selected concrete properties. A new method of introducing SAP into the concrete mix and its impact on the shrinkage and compressive strength of concrete was studied. It was shown that the method of dosing SAP to the concrete mix and the differences in the properties of the tested SAPs have a significant impact on the course of changes of selected properties of the tested concrete composites. In order to compare tested series with each other and with other published results on the subject, a new method of including SAP mass content in the concrete mix, as a percentage of absorbed mixing water, was presented. The effectiveness of internal curing using different types of SAP under different dosing methods was presented as a percentage difference in tested concrete properties between modified series and reference series.
本文研究了用于内部养护的高吸水性聚合物（SAP）的 dosing 方法和材料特性对所选混凝土性能的影响。研究了一种将 SAP 引入混凝土拌合物的新方法及其对混凝土收缩和抗压强度的影响。结果表明，向混凝土拌合物中添加 SAP 的方法以及测试的 SAPs 性能差异对测试混凝土复合材料所选性能的变化过程有显著影响。为了相互比较测试系列以及与该主题的其他已发表结果进行比较，提出了一种将 SAP 质量含量作为吸收拌合水的百分比纳入混凝土拌合物的新方法。在不同 dosing 方法下使用不同类型 SAP 进行内部养护的有效性以改性系列和参考系列之间测试混凝土性能的百分比差异表示。
