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。
On the basis of analysis on the pairwise action of cement paste , nanometer silica fume and clay , the paper proposes the reinforcement mechanism of the cemented soil stabilized with nanometer silica fume . the reinforcement mechanism includes cementation action of cement hydrate , ionic exchange and quadrate reaction of clay particle , pozzolanic effect , filling effect and cementation action of nanometer silica fume 在研究水泥漿?納米硅粉、納米硅粉?粘性土、水泥漿?粘性土相互作用的基礎上，將納米硅粉水泥土的固化機理總結為：水泥水化物的膠結作用、粘土顆粒中的離子交換效應和“二次反應” 、納米硅粉的火山灰效應、納米硅粉的填充效應、納米硅粉的膠結作用。
The result of the experiments shows that the effects of compound pozzolanic and micro - aggregate have been produced when silica fume and slag were added into concrete together . and the stone enveloped with cement can meliorate distinctly the structure of the transition zone of interface , thus the strength of concrete is improved 試驗結果表明：在混凝土中同時摻入硅灰和礦渣可以產生復合火山灰效應和微集料填充效應； “凈漿裹石”攪拌工藝可以大大改善界面過渡區結構，從而提高混凝土的強度。
The results are that : the enhancement effect is improved with the increase of fineness and content of slag powder , but the filling effect will be weakened by excessive fineness and content . the impact on the pozzolanic effect by the fineness of superfine slag powder is changed with content 研究結果表明：增加礦渣微粉的摻量和細度，能夠提高它的增強效應，但是摻量或細度過大都會使填充效應相對減弱；摻量不同，火山灰效應受礦渣微粉細度的影響也不同。
The result shows the high performance concrete ( hpc ) with low w / b normally has denser surface , consuming the ca ( oh ) 2 by pozzolanic reaction and low permeability , which are allowed to restrain effectively the neutralization to decrease the cracking for better durability on concrete 結果顯示，以低水膠比之高性能混凝土，介面頗為致密，卜作嵐反應消耗氫氧化鈣，低滲透性等直接有效的抑制混凝土的中性化，可減低裂縫機率，進而提升混凝土的耐久特性。
