Role of polymers and nano materials in enhancing Engineering properties of cement concrete
Cement concrete is the only material which has been used maximum for construction of buildings. Now the construction technology is accommodating new materials day by day, Inclusion of polymers and nano materials in cement concrete is getting more attention. Polymers and nano materials are improving the engineering properties of the cement and concrete. Newer kinds of cement concrete composites have more compressive and flexural strength along with improved as chemical resistance, impact resistance and temperature resistance. The polymers which have been commonly used are styrene butadiene rubber, polyvinyl acetate. Acrylic polymers and epoxy polymers have been tested for aggressive exposure such as, for high temperature, chemicals exposures etc. with promising results. Nano materials such as ZnO, nano TiO lessThan sub greaterThan 2 lessThan /sub greaterThan , nano ZrO lessThan sub greaterThan 2 lessThan /sub greaterThan , nano Al lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3, lessThan /sub greaterThan nano CaCO lessThan sub greaterThan 3 lessThan /sub greaterThan have also shown improved water resistance, flexural strength, compressive strength and in reducing cement cracks.This article presents an analytical review of enhancement of mechanical properties ; such as compressive strength and tensile strength,due to addition of polymers and nano composites with cement mortar and concrete.
