The cement concrete has attained the status of a major building material in the modern construction because of its various advantages such as its adequate plasticity, remolding characteristics. It is used extensively all over world. But, environmental concerns both in terms of damage caused by the extraction of raw material and the emission of carbon dioxide during the manufacturing of cement have brought pressures to reduce consumption of cement by the use of relatively effective substitute materials. The substitute materials can be mineral admixtures such as fly ash, rich husk, etc. or ultra-fine material such as steatite powder, ultra-fine slag. This paper is based on the compilation of the experimental analysis done by various researchers and scientists. This paper reviews the results of an experimental study, conducted by various authors and researchers to evaluate the strengths and strength efficiency factors of hardened concrete, by partially replacing the cement by various ultrafine materials such as blast furnace slag, fly ash, alccofine, steatite powder, ultra fine calcium carbonate. This reports on the study conducted on the effect of ultrafine slag on the strength of concrete and in order to make an approach to reduce the content of Ordinary Portland Cement which ultimately results in the less carbon emission and less carbon footprints to achieve same or relatively better strength and workability.
