就聚合物共混物对水泥石石英界面结构的影响机理进行了研究,结果表明:在聚合物共混物改性水泥砂浆中,石英表面的水化离解反应因聚合物分子链活性基团的电性作用而失去平衡,导致其表面出现大量带负电荷的[HSiO3]-和[SiO3]2-离子;[HSiO3]-和[SiO3]2-离子与水泥水化阳离子相互作用,在石英表面产生如水化硅酸钙等凝胶状粘结物,从而形成水泥石石英粘附性界面 The effect mechanism of polymer blends on the interface structure of cement stone was studied. The results show that the hydration dissociation reaction of quartz surface in polymer blends modified cement mortar is caused by the reaction of polymer chain As a result, a large amount of negatively charged [HSiO3] - and [SiO3] 2-ions appear on the surface of [HSiO3] - and [SiO3] 2- ions interacting with cement hydration cations. A gelatinous binder, such as hydrated calcium silicate, is produced, forming a cementite-quartz adhesion interface
