近年来，延长混凝土建筑寿命的需求增加，对混凝土效率标准的要求也有所提高。高效减水剂就是用来满足这些要求的。以前的研究已经证实，当高效减水剂在高温环境中沉积时，其物理性质和流动性会发生变化。本研究证实，热刺激对不同粘结剂砂浆的流动性和硬化性能均有影响。结果表明，热刺激效应改善了材料的流动性，但不影响材料的硬化性能。
The demand for extending the life of concrete buildings has increased in recent years, and the requirements of concrete efficiency standards have also increased. Superplasticizers are used to meet these requirements. Previous studies have established that when superplasticizers are deposited in a high-temperature environment, their physical properties and flowability change. This study confirmed that the flowability with different binders and hardening performance of mortars were both affected by thermal stimulation. The results confirmed that the thermal stimulation effect improved the flowability without adversely affecting the hardening performance.
