Through strength tests and xrd tests for cemented stone, the paper presents action mechanism of the nanometer materials in the cement hydration and hardening process : pozzolanic effect, filling effect, acceleration action for the cement hydration, and improving action for microstructure. from the four aspects, the modified mechanism of the nanometer silica fume and ordinary silica fume in cement paste are compared. the analysis results show that the particular properties of the nanometer silica fume include particle fineness, crystal structure and surface hydroxy, etc. a serial of laboratory tests are performed to study physical and mechanic properties of the clay with the addition of the nanometer silica fume
結合水泥石強度試驗和xrd試驗，從火山灰效應、填充效應、水泥水化促進作用和微結構改善作用等方面探討了三種納米礦粉在水泥水化硬化過程中的作用機理；從這四個方面出發，對比分析了納米硅粉和普通硅粉作用機理的異同點，分析表明，納米硅粉的優異特性主要表現為顆粒細度、晶體結構、表面羥基等特性。 -
Based on lots of laboratory experiments and compare of different repairing projects, we think that both the first project and the second project are strengthening repairing and we recommend use the polymer cement mortar as repairing materials. that reason is that, only a very thin layer of cement concrete pavement in qinhuangdao has been loosed and destroyed and it ' s lower layer still satisfy design strength require. it ' s a feasible project to repair the loosing destroy cement concrete pavement
通過對秦皇島市水泥混凝土路面的破壞現狀調查和試驗表明，除水泥混凝土路面表層鬆散破壞外，下面的強度仍然滿足設計強度的要求，通過大量的室內試驗和不同的修補方案的分析比較，課題組選擇了聚合物水泥砂漿作為修補材料，對水泥混凝土路面表層鬆散破壞現象進行功能性養護維修。
