Abstract: 
In this paper, the influence of the system of aggregate coated by silica fume and admixture on the concrete durability was discussed. It showed that the interfacial transition zone between the mortar and aggregate was the week zone of the concrete durability. By the technology of the aggregate coated by silica fume and adding admixture , the resistance to chloride permeability can be multiplied 30 times of the ordinary concrete. Resistance to sulfate can be multiplied above 5 times and the resistance to alternate freezing and thawing can be multiplied above 3 times.
