High-Strength Structural Concrete with Recycled Aggregates

Arem Naresh | Dr. K. Chandrasekhar Reddy [5]

Abstract: Recycled aggregates are comprised of crushed, graded inorganic particles processed from the materials that have been used in the constructions and demolition debris. The aim for this on - going project is to determine the strength characteristic of recycled aggregates for application in high strength structural concrete, which will give a better understanding on the properties of concrete with recycled aggregates, as an alternative material to coarse aggregate in structural concrete. The capacity of this project is to decide and balance the high strength concrete by using special percentage of recycled aggregates. The study was carried out using workability test, compressive test, not direct tensile test and modulus of flexibility test. There were total of eight batches of concrete mixes, consists of each 20 % increase of cast-off aggregate substitute from 0 % to 100 %. In addition, 100 % of recycled aggregate mix batches included fly ash, water/cement ratio of 0.45. The workability of concrete significantly reduced as the amount of recycled aggregate increased. This was evaluated during normal slump test and compacting factor test. For power individuality, the results showed that a regularly falling in compressive strength, tensile might and modulus of stretch as the percentage of recycled aggregate used in the specimens increased.
