A Study on the Absorption Ratio Reduction of Recycled Coarse Aggregate for Concrete Coated by Polymer Dispersions

The purpose of this study is to evaluate the absorption ratio reduction of recycled coarse aggregate for concrete coated by polymer dispersions. The surface of recycled coarse aggregate is treated by polymer dispersion such as SBR and SAE with solid contents of 2%, 5% and 10%. From the test results, The minimum absorption ratio of the coated recycled coarse aggregate is 1.60 times smaller than that of uncoated recycle coarse aggregate. It is apparent that the absorption ratio of recycled coarse aggregate is much more improved by surface coating with polymer dispersions.
