摘要
本研究通过与20±3℃(JIS A 0203:2019)标准养护试件的对比,研究了不同养护剂(No.1-No.6):放水、洒水、水性碱性硅化合物、改性丙烯酸树脂、固体蜡与非离子表面活性剂乳液、水基石蜡对高性能混凝土(HPC)性能的影响。与大多数非标准养护试样相比,按照标准养护养护的试样具有更好的抗压强度和更高的抗冻融能力。然而,特殊的固化剂表现出更高的抗水分渗透和氯离子渗透的能力。
High performance concrete properties with varying curing agents
The Study shed the light on the effects of employing varied curing agents (No.1-No.6): bleeding water, and sprinkling water, aqueous basic silica compound, modified acrylic resin, emulsion of solid wax and nonionic surfactant, and water-based paraffin wax, on the properties of high-performance concrete (HPC) in comparison with the cured specimens according to the standard curing at 20 ± 3°C (JIS A 0203:2019). The specimens cured in accordance with standard curing exhibit a better compressive strength, and higher freeze-thaw resistance compared to most non-standard-cured samples. However, the special curing agents demonstrated higher resistance to moisture penetration as well as chloride ions infiltration.
