Inorganic anti - cracking reinforced chemical additive, called wj, generates some tittle expansive crystals in hydration process in concrete to reduce the porosity and improve the distribution of pore size. the expansive power is process in common to tumefaction that petty crystalloid aft suck water and pressure to concrete pores that aft crystal gather volume. its adding weight was 8 % - - 12 % in cement, its restrained expansive ratio was about 0. 02 % - - 0. 06 %, and relevantil brought self - stress 0. 2mpa ?. 6mpa
無機增強抗裂材料wj摻入普通混凝土中，在水化硬化過程中生成一定量的微膨脹結晶體，降低空隙率，改善混凝土中孔結構分佈。其膨脹驅動力是凝膠尺寸的晶體鈣礬石吸水腫脹和結晶狀鈣礬石對孔隙產生膨脹壓的共同作用。當wj摻量為8一12兒在鋼筋和鄰位的限制下，使混凝土產生0 -
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。 -
To significantly improve both strength and durability of repair interfacial layer between old and new concrete, two attempts were firstly put forward in this thesis : ( 1 ) a kind of new modified primer would be produced by introducing shrinkage reducing admixture into cement mortar, which may both reduce the shrinkage of the interfacial layer, and lessen the content of large crystal in the repaired interface layer, accordingly, remarkably increase the van der waals force of interfacial layer
為大幅度提高新老混凝土修補界面層的強度和耐久性，本文首次提出並實現兩個設想： （ 1 ）以國產減縮劑為外加劑，配製新型改性水泥砂漿界面劑。該界面劑既能減少界面層宏觀干縮裂縫，又不增加大晶體，使界面層形成密實的微細觀結構，顯著提高粘結界面層內晶體間的范德華力。
