Abstract

The present experimental study deals with pre-soaked slurry two stage mixing approach (PSTSMA) for achieving best mechanical properties. The Recycled aggregate was used in three variant as 30%, 50% and 100% replacements of Natural aggregate in M40 grade of concrete. Through experimental study and analysis, it is observed that using PSTSMA the replacement of 30% RCA with natural coarse aggregate does not more affect the characteristics of concrete. PSTSMA method improve up to 6.35% the strength of recycled aggregate concrete made up of recycled aggregate at 28 days respectively w.r.t. Normal Mixing Approach(NMA). It is observed that concrete prepared with PSTSMA gives better properties than concrete with NMA.
