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
