It focuses on the theory of the mineral functional materials " improving the anti - chloride permeability and the chloride binding. the main achievements of this article include : 1 ) use the technology of xrd, sem, bet, laser particle size distributor etc to test the component, the construction, particle size distributor, specific surface etc of micro - silica, ultra - fined slag, high quality fly ash, meta - kaolin clay, four types of the mineral functional material, theoretically analysis the functions which the four mineral functional minerals act on cement concrete, namely pozzolanicity effect, filling effect, micro - aggregate effect, surface adsorption effect and so bring into play the affect of plastification, lowing of temperature, reinforcement, improvement of durability. base on this analysis we can conclude that the proper diameter of the mineral functional material is 5 m - 15 m, that is blain fineness 4500cm2 / g - 7500cm2 / g
本論文的主要成果包括以下幾個方面： （ 1 ）採用xrd 、 sem 、 bet 、激光粒度分析儀等多種測試手段，探明了以硅灰，超細磨粒化高爐礦渣，優質粉煤灰及偏高嶺土超細粉等4種超細礦物功能材料的組成、結構、粒度分佈、比表面積等基本性質；從理論上分析了礦物功能材料在混凝土中的4種效應，即火山灰效應、填充密實效應、微集料效應、表面吸附效應，並由此發揮出增塑、溫峰削減（降熱） ，增強及耐久性改善等作用；通過相關理論分析，推導出礦物功能材料的合理粒徑范圍在5 m 15 m ，即勃氏比表面積為4500cm ~ 2 g 7500cm ~ 2 g 。 -
Gray system study on the influence of particle size distribution of slag powder on performance of cementitious materials
礦渣微粉顆粒分佈對膠凝材料性能影響的灰色系統 -
Therefore it is reasonable that special surface of steel - making slag powder is controlled in the rang between 450 - 500m2 / kg. furthermore, when special surface of different steel - making slag powders are close, steel - making slag powder, which surface is attached lot of fine particle powder or which degree of roundness is high, has higher cementitous property
實驗結果表明，提高比表面積可提高鋼渣粉的膠凝性能，但當比表面積超過500m ~ 2 kg時，鋼渣粉的膠凝性能提高已不顯著，鋼渣粉的最佳比表面積應控制在450 500m ~ 2 kg之間；比表面積相近時，表面有細小顆粒吸附且顆粒圓形度高的鋼渣粉有相對較高的膠凝性能。 -
Generally speaking activity of steel - making slag is higher than first grade fly ash. influence of special surface and particle morphology of steel - making slag powder on cementitous property is studied by experiment. results show that cementitous property of steel - making slag powder increase with increase of its special surface, but increase of cementitous property is not obvious when its special surface is beyond 500 m2 / kg
實驗結果表明，提高比表面積可提高鋼渣粉的膠凝性能，但當比表面積超過500m ~ 2 kg時，鋼渣粉的膠凝性能提高已不顯著，鋼渣粉的最佳比表面積應控制在450 500m ~ 2 kg之間；比表面積相近時，表面有細小顆粒吸附且顆粒圓形度高的鋼渣粉有相對較高的膠凝性能。 -
In order to explore the effects of particls size distribution on structure and properties of cement paste, based on measuring the water requirements of slag with different size distributions on the same fluidity degree, it was revealed the that different size distributions determine different packing densities, and the formula of packing density with continuous particle size distribution for cement paste was developed
摘要為了研究粒徑分佈對水泥石結構與性能的影響，通過測定多組粒徑分佈不同的礦粉在流動度相同情況下的需水量，得到礦粉不同粒徑分佈所對應的不同的堆積密度，推導了漿體中連續粒徑粉體的堆積密度公式。 -
