Abstract: Self- compacting concrete (SCC) has become a choice for a wide range of applications in the construction industry of developed  countries due to several inherent technical advantages over the conventional concrete. But, see has not realized its potential in Indian construction industry. The higher material cost of self-compacting concrete due to requirement of high dosage of Super plasticizer and viscosity modifying agent is always a concern among the users. In this study, an attempt has been made for the manufacturing of economical self-compacting concrete incorporating ASTM class F fly ash. The cost of this see mix based on the cost of materials viz. cement, aggregates, chemical admixtures, was estimated and compared with respect to a conventional plasticized concrete and a pumpable concrete of similar compressive strength , that is, about 40 MPa at 28 days. A comparative study of the manufacturing cost at laboratory for these concrete mixes concludes that see is approximately 16% costlier than the conventional plasticized structural grade concrete and 5% cheaper than a pumpable concrete of similar compressive strength. Further, in-terms of strength developed per unit i.e. MPa, SCC and conventional plasticized concrete are equally costly. Further, advantages and disadvantages of using see technology are also presented in this paper.
