Cement is a binding material, a substance that sets and hardens singly, and can bind other accoutrements together. In ancient civilization the list accoutrements were of traditional type similar as jiggery, lead, jute, rice coconut etc., now in ultramodern civilization cement is main in the list of accoutrements. The use of concrete containing high volume of fly ash has lately gained fissionability as a resource effective, durable and sustainable option for variety of concrete operation (1). The use of fly ash in concrete at proportions in ranging from 30% to 65% of total cementitious binders has been studied considerably over the last twenty years. In present research cement is replaced by fly ash with suitable proportions. Target strength of M20 grade is fixed, by replacing cement with high volume fly ash as per the normal blend design (2). M20 target tensile strength is gained by replacing cement 60% of its mass by fly ash. Cylindrical specimens were cast and tested for 7 and 28 days. Thirty six concrete specimens were cast and tested in this design. Out of which eighteen were for 7 days and another eighteen for 28 days. Cement has been replaced with fly ash i.e., C100F0, C80F20, C60F30, C50F50, C30F70, C10F90, COF100. Eventually good strength results obtained by replacing the cement with fly ash (3, 4).
