【摘要】 分析了Thaum asite的物相结构特征、生成条件和破坏机理;与常规硫酸盐侵蚀对混凝土结构的破坏作用不同,它的生成直接导致水泥石中C SH凝胶体分解,使混凝土最终变为无强度泥状混合物。针对我国西部和北部开发,提出预防混凝土结构发生此类侵蚀破坏的方法。更多还原

【Abstract】 Structural characteristic, forming mechanism and the conditions conducive to formation of thaumasite are discussed. In contrast to traditional sulfate attack on concrete, thaumasite formation results in decomposition of CSH gel in cement paste and attacked concrete becomes a mushy and friable mixture. Some methods of preventing newbuild concrete structures from this type of attack are advised for construction engineerings in the western and northern regions.更多还原
