Use of Recycled Aggregate and Fly Ash in Concrete IJERT

Apr 24, 2018 In general, the RCA (Recycled Coarse Aggregate) has high water absorption due to the cement paste from old concrete. It will result in the inferior material properties of recycled aggregate concrete. Presently, the mix design with RCA was developed to get the desired amounts fly ash and recycled aggregate.

Use of recycled concrete aggregate in fly-ash concrete

This paper discusses the effect of both partial and full replacement of natural coarse aggregates by coarse RCA in a fly ash concrete. Engineering properties and durability performance have been examined on both concrete types (Portland cement and fly ash) for mixes designed with various proportions of the RCA (0%, 30%, 50% and 100%) by mass.

Effect of Fly Ash on Recycled Aggregate Concrete

Hence a popular concrete mix 0.5:1:1:2 was used in this study for experimental purpose. Fly ash confirming to IS 3812:2003 was used as a part replacement of cement. Fly ash was replaced by cement in % of 0%, 10%, 20%, 30% and 40%. Again natural aggregates were replaced by recycled coarse aggregates (RCA) in % of 0%, 10%, 20%, 30% 50% and 100%.
