Investigating and Presentation Solutions for Concrete Corrosion in Coastal Structures

In our country consumption of concrete has become widespread recently.Understanding the nature and function of concrete and most importantly the proper use of it is very important.Inappropriate behavior with concrete may have two aspects (Samaee F, Samaee A. 2005):1) Calculation 2) Lack of coordination with surrounding environment Concrete should be durable and in general it should not be ruined earlier than expected.Durability of concrete made from Portland cement is its strength against weathering, abrasion, chemical attack and other aggressive agents (Samaee F, Samaee A. 2005).Destruction of concrete can be seen in the form of cracking, dandruff, scaling, rusting and so on.Concrete can be obtained with favorable resistance in coastal area by reviewing the general rules and regulations (Samaee F, Samaee A. 2005).Fire causes a dangerous menace to the life of the structure and inhabitants, as it enforces damaging results at the structural area both tiny term and lengthy term.The security and the operative life of concrete constructions after experience to fire depend on two significant reasons i.e. residual stability and resistence.Reuse concrete aggregates sourced from waste concrete are a tolerable intermittent to intrinsic squashed stone aggregates.The factors examined in the empirical investigation are watercement ratio, cement constituents in concrete and percentage substitution of rough aggregate.Durability features such as water sorption, sorptivity, acid attack persistence, and chloride penetrance are also specified.A mix plan methodology applying the expanded patterns is suggested to support exercising engineers to specify the mix ratios of reused concrete aggregates concrete.Applying frequently reused rough aggregate to provide structural concrete is an essential means for directing the economic, environmental, and social issues effected by the lack of natural aggregate resources.The consequences display that the qualities of the reused rough aggregate that result in the durability of concrete spoil with an enhancing number of reprocessing cycles.Durability standards of the reused rough aggregate (freeze-thaw persistence, chloride ion penetrance factor, and carbonization depth) reduce regularly with an enhancing number of reusing cycles.However, the reused rough aggregate in Abstract: Concrete has used extensively in coastal areas especially marine structure due to its easy access and relatively high compressive strength, toughening and ductility during construction and long durability.High humidity in coastal areas has exacerbated the corrosion of metal and as a result concrete as a durable and resistant material has a special position in marine work and adjacent seaside buildings.Concrete corrosion in coastal structures causes a lot of economic losses to us and we can prevent this damages by providing appropriate solutions in the field of construction.In this paper we first examine the types and circumstance of concrete corrosion in coastal structures and then discuss the construction and use of reinforced concrete in coastal structures.
