【摘要】 为考察机械力化学对单组分地聚物粉体的比表面积、粒度以及净浆抗压强度的影响，进行了机械力化学制备单组分地聚物的试验研究，并进行同配比条件下的简单混合对比试验，同时通过X射线衍射(XRD)、同步热分析(DTG)、傅里叶红外光谱(FTIR)等技术分析机械力化学的作用机制。研究结果表明：机械力化学制备单组分地聚物，其比表面积较简单混合有明显增大；机械力化学制备的单组分地聚物净浆不同龄期的抗压强度较简单混合制备均有较大提高。分析可得，机械力化学能够有效细化单组分地聚物粉体颗粒粒径，提高反应活性，促使反应更早发生，从而改善其宏观特性。研究成果能为机械力化学制备单组分地聚物的工程应用提供参考依据。更多还原

【Abstract】 To investigate the effect of mechanical activation on the specific surface area and particle size distribution of one-art geopolymer powder and the compressive strength of paste, the experimental study of one-part geopolymer prepared by mechanochemistry and the comparison test of simple blend under the same mix proportion were conducted.The experiments were conducted to investigate the effects of the two different preparation methods on the specific surface area of the powder and the compressive strength of the paste.The mechanism of mechanical activation was revealed by XRD,DTG,and FTIR techniques.The results showed that the specific surface area of the one-part geopolymer prepared by mechanical activation increased significantly compared with that of the simple blend.The compressive strength of the one-part geopolymer paste prepared by mechanochemistry at different ages increased significantly compared with that of the simple blend.From the analysis, it can be concluded that mechanochemistry can effectively refine the particle size of the one-part geopolymer powder, increase the reactivity, and promote the reaction to occur earlier, thus improving its macroscopic properties.The results of the study can provide a reference for the engineering application of the one-part geopolymer prepared by mechanochemistry.更多还原
