Drastic growth in Demolition waste projects in India, there is tremendous amount of Construction Demolition Waste generated by milling and digging of existing demolition waste. Even though CDW gets recycled in new demolition waste, there is still large volume of this material that gets downgraded, especially in urban areas. Therefore, there is a need to effectively utilize the unused CDW in construction industries. The ultimate goal of the present study was to wider the current knowledge about the Construction Demolition Waste as aggregates in alkali-activated concrete paver blocks. The geopolymer paver blocks were then made and tested for compressive strength, dimension, water absorption and aspect ratio. The result was observed that the compressive strength of the blocks increases with increase in Molarity of Alkali solution. The water absorption was within limit. The results for dimensions and tolerances along with the limitations for length, width, and thickness are within the tolerance limits as per IS 15658–2021.
