Properties of Environmental Friendly Recycled Polymer Concrete

Recently, the study for practical construction application of recycled aggregate concrete is actively being proceeded, on the purpose of technical development for recycling on the construction waste concrete occurred at the time of destruction of building construction by the rapid increase of building wastes and exhaustion of natural aggregates. This study is performed to develop the permeable polymer concrete using recycled coarse aggregate and blast furnace slag for application of structures needed permeability. At 7 days of curing, compressive strength, flexural strength, water permeability and flexural load are in the ragge of $18\~20MPa,\;6\~7MPa,\;4.6\times10^{-2}\~6.9\times10^{-2}cm/s$ and $20\~25kN$, respectively. It is concluded that the recycled aggregate can be used in the permeable polymer concretes.
