Performance Evaluation of Polymer Modified Concrete Using Polyurethane and Poly (Vinyl Alcohol Co-Ethylene)


Concrete made with portland cement is the most widely used construction material. However, concrete can present some disadvantages, such as delayed hardening, low tensile strength, relatively high drying shrinkage and low chemical resistance. Polymer-modified concrete (PMC) is an alternative material that has been employed in construction applications. PMC is made by modifying ordinary concrete with polymer additives, such as latexes, redispersible polymer powders, water-soluble polymers or liquid resins. the aim of this study is to investigate the effect of cost-effective polymers, namely polyurethane (PU) and poly (vinyl alcohol co-ethylene) (PVACE) in improving the flexure strength and compressive strength of portland cement concrete. the coarse aggregate was precoated with either PU or with PVACE polymer prior to its placement in a cement matrix. the effect of different polymer contents was measured for treatment levels of between 30% to 100% of treated aggregate for PU or from 2 to 30 mg/m2 mass of PVACE per aggregate surface area. the results indicated that the incorporation of 12 mg/m2 of PVACE lead to an increase in the flexure strength of concrete of approximately 12%.
