Review on Polymer Modified Concrete and its Application to Concrete Structures

Use of polymer modified concrete as a construction material in structural applications has been increased in recent years. Polymer concrete has excellent strength and durability properties. Looking into the advantages of polymer modified concrete, an exhausted literature survey has been carried out to study its uses and effect on various properties of the concrete and presented in this paper an attempt has been made to present review on polymer modified concrete and its application to concrete structure which will be very useful to civil engineers to known its application in construction industry. It is well known that some concrete structures constructed with high performance materials start to deteriorate long before reaching their designed service life. In such cases cracks are caused after the structure has been completed for a few years. It leads to results in the shortening of service life and lowering in durability. Durability modification in concrete must be considered in construction. Moreover, other factors may be considered like cracking and debonding, which allows chloride,carbon dioxide or detoriative agents penetrate through structural members. Polymers have been employed as concrete admixtures. Based on the mode of their addition, polymer cement concrete is classified as- polymer modified cement concrete or mortars (PMC/PMM), polymer concrete or mortars(PC/PM), polymer impregnated concrete or mortars (PIC/PIM).
