有在在水泥灰浆的加入以前的三乙氧基甲硅烷偶合剂的硅石烟的表面处理导致了在 10 percent-20 百分比由 5percent-200% 和储能模量在损耗角正切值展出增加的 composites,相对使用同样收到的硅石烟获得的价值。扫描电子显微检查法(SEM ) 图象显示在水泥粘贴与有 rnorphological 差别对待并且同样收到的硅石烟。TheX 光线衍射(XRD ) ,红外线(红外) 光谱分析和水银侵入 porosimetry (MIP ) 提供了证据理解在对待的硅石烟和水泥的水合物产品之间的反应机理。这导致了描述水泥矩阵的抑制行为的一个起始的显微镜的模型的建立。
The surface treatment of silca fume with silane coupling agent prior w incorporation in a cement mortar resulted in composites exhibiting increuses in loss tangent by 5%-200% and storage modulus by 10%-20% , relative to the value obtained by using as-received silica fume. The scanning electron microscopy (SEM) images iindicate that there is a morphological difference in the cement paste with treated and as-received silica fume, The, X-ray diffraction (XRD), infrared (IR) spectrum analyses and mercury intrusion porosimetry ( MIP ) have provided evidence to understand the reaction mechanism between treated silica .fume and the hydrate product of cement. This has led to the establishment of an initial microscopic model describing the damping behavior of cement matrix.
