Author Name V.Sravani and D.Mohammed Rafi Abstract The various studies related to sustainable concrete construction have encouraged recycled aggregate which is a partial replacement of natural aggregate in concrete mixes. The significance of silica fume (SF) in concrete mix will improve the quality of recycled aggregates in concrete. The Portland cement was replaced with Silica Fume at 0%, 5% and 10%. The coarse aggregate in concrete mix is replaced by 0%, 25%, 50%, 75%, and 100% of recycled coarse aggregates (RCA). The compressive strength and split tensile strength of concrete made with recycled aggregates are evaluated. Manufacturing of recycled aggregate concrete with silica fume consists of different methods to increase the strength of RCA such as surface treatments, three stage mixing and pozzolanic material. In this paper, the method of using pozzolanic material is studied. In this silica fume is used as pozzolanic material. Keywords: Recycled aggregate, recycled coarse aggregate concrete, Silica fume, Compressive strength, Split tensile strength. Published On : 2022-11-15 Article Download :
