Polymers in Concrete: Applications and Specifications

The use of polymers in concrete has a very long history. Over the past 25 years many researches have been conducted on polymer. Due to the high impact of polymer on structures and concrete procedures, these studies are ongoing. Polymers improve mechanical and chemical properties of concrete, some of which include increased compressive strength, flexural and tensile strength as well as good performance in increasing durability and reducing corrosion and permeability of concrete. Generally, there are three types of concrete which is made by polymer including polymer impregnated concrete (PIC), polymer concrete (PC) and polymer modified concrete (PMC). In this article, we have tried to review the history of using polymers in concrete as well as reviewing techniques and modern researches in the construction and improvement of this type of concrete
