Behavioural study of pavement quality concrete containing construction, industrial and agricultural wastes

Fly ash admixed mixes showed a gain of 15% and 24% for compressive and flexural strength parameters, while the gain for rice husk ash mix and bagasse ash mixes was observed to be 12% and 25%, 13% and 20% respectively when compared to recycled aggregate concrete mix without mineral admixtures. Improvements in durability aspects were observed by incorporating mineral admixtures supported by lower parameters for water absorption, sorptivity coefficients and chloride ion concentrations and increased hydration products as concluded from scanning electron microscopic investigations.
