This paper presents a comprehensive approach to elucidate the mechanical and thermal aspects of coating layers integrated with organic-based PCMs. In that respect, three sets of cement mortars were studied experimentally to underline the significance of PCMs proportion. From a mechanical point of view, the strength of specimens cured at 20 °C resulted to be superior compared to 40 °C, with a more evident influence for cement mortars containing PCMs. Laboratory tests on specimens subjected to 50 wetting–drying cycles demonstrated an insignificant increase of the mass for coatings without PCMs and a slight increase for coatings containing PCMs. During this process, growth in strength for the base mix without PCMs and a loss in strength for mixtures with PCMs was exposed; an exponential decay relationship was noted between the compressive strength with the PCM proportion. Alongside this, a transient thermal analysis was carried out to assess the effect of PCMs on the dynamic thermal parameters of coating layers. A higher proportion of PCM ingredients leads to enhanced responsiveness since the heat wave penetrating the layer is smoothen and delayed. These issues can adequately address the defensive behaviour capacity of building components, without surpassing their carrying structural stability and mechanical properties.

本文提出了一种综合方法来阐明与有机基 PCM 集成的涂层的机械和热方面。在这方面，通过实验研究了三组水泥砂浆，以强调 PCMs 比例的重要性。从力学角度来看，与 40 °C 相比，20 °C 固化的试样强度更高，对含有 PCM 的水泥砂浆的影响更为明显。对经受 50 次干湿循环的试样进行的实验室测试表明，不含 PCM 的涂层的质量没有显着增加，而含有 PCM 的涂层的质量略有增加。在此过程中，暴露了不含 PCM 的基础混合物的强度增长和含 PCM 的混合物的强度损失；压缩强度与 PCM 比例之间存在指数衰减关系。除此之外，还进行了瞬态热分析以评估 PCM 对涂层动态热参数的影响。较高比例的 PCM 成分可增强响应性，因为穿透层的热浪会被平滑和延迟。这些问题可以充分解决建筑构件的防御行为能力，而不会超过其承载结构稳定性和机械性能。较高比例的 PCM 成分可增强响应性，因为穿透层的热浪会被平滑和延迟。这些问题可以充分解决建筑构件的防御行为能力，而不会超过其承载结构稳定性和机械性能。较高比例的 PCM 成分可增强响应性，因为穿透层的热浪会被平滑和延迟。这些问题可以充分解决建筑构件的防御行为能力，而不会超过其承载结构稳定性和机械性能。
