Abstract: Cement is one of the most significant constituents of concrete. Most of the properties of concrete depend on cement. By calcining argillaceous and calcareous material at a high temperature in cement production. During this procedure, huge amount of Co2 is discharged into the air. India is the second biggest manufacturer of cement on the planet. It is assessed that the generation of one tonne of cement brings about discharge of 0.8 tonne of Co2 . The decline in the utilization of cement will lessen the cost of concrete and outpouring of Co2 . Dolomite powder acquired by pulverizing rock forming mineral deposit of dolostone can be utilized as a trade material for cement in concrete up to certain percentage. Dolomite powder has a few comparative attributes of cement. Utilizing dolomite powder in cement can diminish the expense of cement and may expand the solidarity somewhat. Dolomite powder is a pozzolonic material which will improve not only the density but also strengthen the hardness of concrete. This paper inspects the likelihood of utilizing dolomite powder as partial substitution material to cement. The substitution rates attempted were 0 to 25% at a regular interval of 5% by weight of cement. The outcome demonstrates that substituting of cement with dolomite powder improves the compressive, split tensile and flexural strength of concrete.
