- Abstract
- This paper presents the effect of polymer type and specimen size on the strength properties of concrete-polymer composite. The aim of this study is to determine the compressive strength and the stress-strain behavior of the test samples. Three different types of polymer are used; poly-propylene (PP), Low Density Polyethylene (LDPE), and Poly-VinylPyrrolidene (PVP), with different additives to modify the cement concrete matrix. By means of compressing loading method, the compressive strength and stress-strain properties of polymer modified concrete are measured. The effect sample thickness on the mechanical properties is also investigated. The results demonstrated that the polymer-modified concrete, made with a hybrid layer of (PP+PE) shows maximum enhancement in tensile stress and ultimate strain with ratio about 42% , and 33% respectively. The results show that The compressive strengths of polymer concrete composite were not enhanced by the addition of (PVP) fine powder.
