| 中文摘要: |
| 早强剂作为混凝土常用外加剂，可有效地提高混凝土的早期强度。本文通过微量热法和水泥胶砂试验，研究了硫氰酸钠、硫酸钠、硫酸铝等早强剂对水泥早期水化和强度的影响，并对其相关作用机理进行了阐述；同时采用多项评价指标，综合对比了相同掺量下不同早强剂的早期水化及早强效果。 |
| 英文摘要: |
| As a commonly used admixture for concrete, early strength agent can effectively improve the early strength of concrete. This article investigates the effects of early strength agents such as sodium thiocyanate, sodium sulfate, and aluminum sulfate on the early hydration and strength of cement through microcalorimetry and cement mortar tests, and elucidates their related mechanisms of action; At the same time, multiple evaluation indicators were used to comprehensively compare the early hydration and early strength effects of different early strength agents under the same dosage. |
