本文研究了水蒸气爆炸法制备的木纤维束（WFS）与水泥混合后的水化行为和强度性能。在目前的研究中，水泥爆炸WFS界面区的微观结构特征进行了研究，使用扫描电子显微镜与能量色散X射线能谱仪（SEM-EDS）。研究了界面区的Ca/Si比和管胞腔中沉积的水化产物的元素组成。此外，形态差异和成分变化的水化产物，开发的木材表面进行了检查。结果表明，在界面区的Ca/Si比的强烈影响的混合物的组成，和填充管胞腔的水化产物的元素组成是显着不同的混合物中的水泥浆。在木材表面的水化产物的形态和组成的差异也观察到对应于不同的混合物组合物。这些特性被认为是直接相关的粘结性能，因此，对水泥混凝土的机械性能。
The hydration behavior and strength performance of cement mixed with exploded wood fiber strand (WFS) obtained by the water-vapor explosion process have been studied previously. In the current study, the microstructural characteristics of cement–exploded WFS interfacial zone were examined using scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS). The Ca/Si ratios at the interfacial zones and the elemental compositions of hydration products deposited in the tracheid lumen were investigated. In addition, the morphological differences and compositional variations of hydration products that developed on the wood surfaces were examined. The results revealed that the Ca/Si ratios at the interfacial zones were strongly influenced by the mixture compositions, and that the elemental compositions of the hydration products that filled the tracheid lumen were significantly different from those of the cement paste in the mixtures. Differences in morphology and composition of hydration products at the wood surfaces were also observed to correspond to the different mixture compositions. These characteristics are considered to be directly related to the bond property, and thus, to the mechanical performance of WCM.
