摘要
通过(?)动电位、吸附量测定,TGA-DTA热形成机理和SEM的形貌观察,对合成的氨基磺酸盐高效减水剂SR改性水泥基材料进行了研究。结果表明:SR的性能优于其他减水剂,并对改性作用机理进行了分析。
By means of tests on ζ dynamic potential, adsorption, analysis of TGA-DTA heat formation mechanism and SEM observation of morphology, study was carried out of cement-based material modified by synthetic amino sulfonate superplasticizer SR, Testing results showed that performance of SR was superior to those of other water reducers, Mechanism of modification was analysed.
