Worldwide CO2 emission has been done by various agencies and reported their roots. The one most emerging and well known contributor of CO2 emission is the cement manufacturing. Now a days, cement manufacturing work out in practice are 1.7 x 109 t/year and it creates 7-8% worldwide greenhouse gas emission. Where the infrastructural growth depends on concrete production and concrete making process needs the binder material as a cement. Cement production has produces 900kg of CO2 per thousand kilogram of cement consumption and it’s definitely doubled in 2050, if other binder material inventions not happened. Therefore as considering a crucial role of binder material, fly ash material can play same or partial role as alternative material to cement. This study mainly introduces fresh fly ash concrete behavior for sustainable adoptability. Fly ash concrete more feasible (cheaper), scale down permeability, boost strength and influence other concrete properties. This paper is useful for assessing workability issues by providing 54 test results of slump cone and compaction factor test
