Curing compounds are widely used materials that are used in place of other methods of curing fresh concrete. The article presents an overview of the effectiveness of the concrete curing compounds widely used in Europe. Eleven different products have been tested. FTIR spectroscopy identification tests showed that all tested products might be divided into two main groups, depending on the type of their active substance. The water retention efficiency of each curing compound was examined, and the tensile strength of the cured samples was tested using the pull-off method. The dry mass content of the tested products was examined to check for a correlation between their effectiveness and active substance content. The microstructure of mortars treated with the most effective compounds and the reference mortar were examined using SEM techniques. Significant differences in microstructure were found between cured samples with different curing compounds, and also with uncured samples.
养护剂是广泛使用的材料，用于替代新拌混凝土的其他养护方法。本文概述了欧洲广泛使用的混凝土养护剂的有效性。测试了11种不同的产品。傅里叶变换红外光谱鉴定测试表明，根据其活性物质的类型，所有测试产品可分为两个主要组。检测了每种养护剂的保水效率，并使用拉拔法测试了养护样品的抗拉强度。检测了测试产品的干质量含量，以检查其有效性与活性物质含量之间的相关性。使用扫描电子显微镜技术检查了用最有效化合物处理的砂浆和参考砂浆的微观结构。发现使用不同养护剂养护的样品之间以及未养护样品之间的微观结构存在显著差异。
