▎ 摘  要

NOVELTY - Manufacturing polymeric waste derived nanographitic additives for concretemixture comprises: synthesizing graphene or its derivatives using solid waste materials e.g. waste plastic orrubbers/tire or agriculture waste;assimilating graphene and derivatives into cementing mixture to enhance mechanical andtensile properties drastically;treating nano reinforced materials by adding grade 43 ordinary portland cement with suitablemixing of fine aggregates, natural coarse aggregates in 1:1.89:2.87 ratio for the preparation of concrete blocks; mixing the solution through magnetic stirring with high rotation capability in controlled heating of 40-60 degrees C; and adding 0.5-3% superplasticizer by weight of cement to increase the strength anddurability of graphene mixed concrete. USE - The process is useful for manufacturing polymeric waste derived nanographitic additives for concretemixture (claimed). ADVANTAGE - The process: provides a high mechanical and tensile strength ofcement concrete by low budget mass manufacturing of graphene as nanofiller in costeffective manner; and increases the strength and durability of graphene mixed concrete.
