NOVELTY - Manufacture of polymeric waste derived nanographitic additives involves mixing superplasticizer for reducing water uptake tendency of cementing concrete materials, into solid waste materials such as waste plastic or rubbers/tire or agriculture waste through a magnetic stirrer, developing of sets of concrete mixtures blocks having different ratio of waste derived graphene along with pure blocks, assimilating graphene or its derivatives, reducing graphene sheets into cementing mixture to enhance its mechanical and tensile properties drastically, producing nano reinforced concrete blocks using 43-grade ordinary Portland cement by stabilizing the mixture for 24-30 hours and opening the blocks after 30 hours the blocks to obtain exact square shape and equivalent size block comprising zone II fine aggregates used along with the natural coarse aggregates having particle size of 10-12.5 mm, and testing mechanical strength of the blocks with both fresh and hardened sample at the aging. USE - Manufacture of polymeric waste derived nanographitic additives used in concrete mixture for building and civil engineering applications. ADVANTAGE - The method enables economical manufacture of polymeric waste derived nanographitic additives having excellent mechanical strength, durability, and tensile strength, and provides concrete mixture having excellent flowability, and water-repelling property, by using graphene and its derivative. DETAILED DESCRIPTION - Manufacture of polymeric waste derived nanographitic additives involves mixing superplasticizer for reducing water uptake tendency of cementing concrete materials, into solid waste materials such as waste plastic or rubbers/tire or agriculture waste through a magnetic stirrer with high rotation capability in controlled heating of 40-60 degrees C, developing of sets of concrete mixtures blocks having different ratio of waste derived graphene such as 0.10%, 0.5%,1.0%,1.5%, along with pure blocks, assimilating graphene or its derivatives such as graphene oxide, reducing graphene sheets into cementing mixture to enhance its mechanical and tensile properties drastically, producing nano reinforced concrete blocks using 43-grade ordinary Portland cement by stabilizing the mixture for 24-30 hours and opening the blocks after 30 hours the blocks to obtain exact square shape and equivalent size block comprising zone II fine aggregates used along with the natural coarse aggregates having particle size of 10-12.5 mm, and testing mechanical strength of the blocks with both fresh and hardened sample at the aging of 7 days, 14 days, 21 days, and 28 days. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of preparation of polymeric waste-derived nanographitic additives.
