Abstract The present research work has been carried out for accessing the effect of utilisation of 100% coarse recycled concrete aggregates and 0–35% rice husk ask (RHA) in designing concrete mixes. For this, 5%, 10%, 15%, 20%, 25%, 30% and 35% of rice husk ash has been introduced in natural aggregate concrete (NAC) and recycled aggregate concrete (containing 100% coarse recycled concrete aggregates) as replacement of cement. Different properties of aforementioned designed concrete mixes such as workability, 7, 28 and 90 days compressive strength, spilt tensile and flexural strength, modulus of elasticity, non-destructive parameters (rebound number and ultrasonic pulse velocity), water absorption, density, volume of voids has been determined. The analysis of experimental results depicts that the behaviour of concrete substantially is influenced by the incorporation of coarse recycled concrete aggregates and rice husk ash in concrete. However, concrete mixes containing 100% coarse recycled concrete aggregates and 10–15% rice husk ash satisfies the design requirements for application in construction industry.

- Quality Improvement Techniques for Recycled Concrete Aggregate: A review (2019, methodology): “…compressive strength for new concrete containing RCA after applying the different mixing approaches (DM and TM) with pozzolanic materials (fly ash (F) and slag (S)) compared to NM. Padhi et al. (2018) studied the effect of using 5 - 35% rice husk ash (RHA) in designing concrete mixes with 100% RCA.”
