Effect of Polymer modification on mechanical and structural properties of concrete – An experimental investigation

This paper presents the effect of different polymers on structural and mechanical properties of concrete. The aim of this study is to investigate the mechanical and flexural properties of polymer modified concrete. Two different types of polymers are used at different dosages to modify the cement concrete matrix. Besides, a series of tests without modification was also carried out. By means of four-point loading method, the flexural strength and flexural properties of polymer modified concrete are measured. The influence of different polymers and its optimum dosage in respect of flow and strength characteristics are found. A comparative study has been carried out to highlight the effect of two different polymers on fresh and hardened properties of polymer modified concrete. Based on these results, recommendations are made in respect of its dosage, chemical characteristics and suitability.
