Concrete as known globally is the most widely used construction material in all type of construction works. Recycled concrete aggregates have been eyed as a viable option for part replacement of natural coarse aggregates for concrete production by researchers for quite some time. However, their tendency to bring down the property parameters of new concrete makes it very important to investigate the extent of variation in durability properties of fresh concrete incorporating recycled concrete aggregates. Mineral admixtures are believed to improve the durability and mechanical aspects of concretes. This study makes an effort to understand the effects of incorporating recycled concrete aggregates and different mineral admixtures on durability aspects of pavement quality concrete mixes. In order to investigate the same, recycled concrete aggregates were used along with mineral admixtures in different proportions to study the variation in properties. Concrete mixes prepared with natural aggregates, recycled concrete aggregates and mixes containing recycled concrete aggregates and mineral admixtures were prepared and tested for variations in their durability properties. Laboratory investigations revealed that incorporating mineral admixtures does improves the durability aspects of pavement quality concrete having recycled concrete aggregates. Reduction in values for water absorption, sorptivity coefficients and chloride ion concentrations supported better durability aspects for mixes prepared with recycled concrete aggregates incorporating mineral admixtures.
