Strength Characteristic of Recycled Aggregate with Silica Fume as Admixture

In this study, conventional concrete is developed using recycled aggregates with micro silica (silica fume) as admixture. The mix designed for target strength of 25 MPa. Coarse aggregate were partially at 15 %, 30 % and 45 %. relative parameters influencing the studied in terms content respectively. Test results reveled produced 45% tend to reduce by 12% whereas addition fume (10%) enhances comparable control (M25). Addition microsilica functions microfilling action unreacted core which physical mechanical properties concrete. significant reduction compressive noticed, when increased beyond 30%.
