Concrete structures Projects under construction near wetlands cause harmful substances to enter the wetland and thereby escape or death of animals, wetland accumulation from artificial sediments, chemical change of water, etc. Using pozzolans as well as environmentally friendly concrete is a good way to reduce harmful substances.. In this research conducted in Anzali International Wetland, the effect of constructing concrete foundations along the road of Anzali port on the pollution of the wetland was investigated and the amount of chemical changes of the sample prepared in the wetland water by different concrete, one concrete made with Portland cement and another Portland blend concrete and fused micro-silica gel. The results of this study showed that by reducing the concrete content of 8% and adding the same percentage of fused micro-silica gel to the concrete volume of the bridge bridges, while increasing the bridge's resistance, Biodiversity and pollution of the wetland water also occurred in the environmental assessment of the bridges Concrete and metal found that it is more suitable to produce less pollutants in the process of manufacturing metal bridges. Addition of fiber-reinforced silica gel resulted in less change in the chemical quality of water than in cement-based concrete, and only due to the presence of silica, the amount of silicon element was greater than that of cement-based concrete.
