Use of recycled concrete aggregate in fly-ash concrete ...

Highlights This research investigates the use of RCA as substitute of NA in fly-ash concrete. RCA is shown to be an efficient alternative material to natural aggregates. 30% replacement of NA by the RCA has found to be the optimum replacement level. FA-concrete with 30% RCA has exhibited a quite similar performance to NA concrete. Using RCA in blended cement concrete is more efficient than in ...

Effect of Fly Ash on Recycled Aggregate Concrete

Again fly ash is also a by product from various industries. Hence a study was needed to arrive at various combinations of both of these materials. 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.
