Experiment on concrete containing with activated carbon and nano-fly ash, nano metakaolin

Abstract

Concrete is a versatile material having many advantages. Hence it is the most widely used material in the construction industry. Many researchers made attempts to use waste materials with the objective of eliminating the disposal problems and at the same time improving the properties of concrete. An attempt has been made to improvethe compressivestrength of concrete with activated carbon, Nano fly ash (NF) and Nano metakaolin (NM). In this work, the concrete mix was prepared by replacing cement with 20 %(NF) and 10% (NM). Further, the concrete mix is added with 0.4%, 0.8%, 1.2%, 1.6%, 1.8% and 2% of activated carbon. The compressive strengths of cement were evaluated after 28days of curing. It is observed that the concrete mix added with 1.2% of activated carbon exhibited the maximumstrength. The maximum increase in the strength was found to be 25% more than that of the concrete without Activated Carbon.
