Abstract

Concrete is the material that has the greatest versatility and widespread use in construction
 worldwide. 
The durability of concrete structures has become a major concern in recent years  . Particularly in 
environments with high levels of aggression. Traditionally, a large number of natural and  Chemical 
admixtures are used to enhance concrete's properties.  
In  the majority of concrete failures are caused by mistakes in material design and installation .
 workmanship, environmental impact, usage, and poor maintenance strategy are all factors to consider. 
The durability  of concrete can be influenced by a range of physical and chemical factors. Relevant 
choice of Concrete's strength and durability can be improved by adding admixture . 
The purpose of this paper is to review the literature of several published studies on the impact of 
chemicals aggression to reinforced concrete structures.
