However, except for a few EU countries, only about 50% of C&DW is currently being recycled. In the present research, the environmental impact of concrete with recycled aggregates and with geopolymer mixtures is analysed.Use Of Recycled Aggregate In Concrete IJERT,Use of recycled aggregate in concrete can be useful for environmental protection. Recycled aggregates are the materials for the future. The application of recycled aggregate has been started in a large number of construction projects of many European, American, Russian and Asian countries.
The use of recycled concrete aggregate (RCA) as an alternate for dense-graded aggregate base course (DGABC) applications over the recent years have been approximately 10% to 15%.Presently 60 to 70 percent of demolished concrete is using as sub-base course aggregate for road construction.Application of Recycled Structural Concrete to Replace of,Application of Recycled Structural Concrete to Replace of Coarse Aggregate under the Building Control Laws and Construction Standards written by Punkorn Cheewawutwatanawit,Dr. Waranon Kongsong, Dr. Krisda Bisalyaputra published on 2019/08/23 download full Application of Recycled Concrete for Structural Concrete,Title: Application of Recycled Concrete for Structural Concrete- Experimental Study on the Quality of Recycled Aggregate and Recycled Aggregate Concrete Author(s): Y.
