Abstract: The use of mineral and chemical admixtures in concrete is a common solution to achieve full compaction particularly where reinforcement in congestion. The paper has been made an attempt to study the influence of four different naphthalene based super plasticizers with a dosage of 0.2,0.4,0.6,0.8,01,1.2 percent on performance of concrete .The present experimental procedure which gives immense help to the researcher to understand the behaviour of naphthalene based super plasticizer on property of fresh, hardened and durability property of concrete. In the present project work grade of concrete M30 is used for the study and four type of super plasticizers ( Chloride free sulphonated naphthalene polymer, Naphthalene Formaldehyde condensate, Sulphonated Naphthalene formaldehyde condensates, Modified Naphthalene formaldehyde condensates ) are used for present study. The super plasticizer is replaced with different dosages by weight of cement. The fresh properties of super plasticized concrete is studied on the results of , slump test, compaction factor test , vee-bee consist meter, it is observed that (Chloride free sulphonated naphthalene polymer, Naphthalene Formaldehyde condensate, Sulphonated Naphthalene formaldehyde condensates, Modified Naphthalene formaldehyde condensates) 0.6% dosage shows better performance with conventional concrete. Relatively the hardened and durability of super plasticized concrete is studied

Keywords: Super plasticizers, workability
