Concreteis the most extremely used construction material within the world, which always uses natural resources like lime, aggregates and water. The production of cement in world has increased greatly, due to this cementproduction emission of CO2 gas has been increased tremendously, ultimately environmental pollution increased to very large extent. This affect to environment has been reduced by cement has been replaced by some supplementary materials like Dolamite Powder or Fly ash or GGBS &so on. Dolamite. Powder was conducted detailed study and lots of research work has been made on other waste materials and it is found there is a great future scope for research on Dolamite Powder as a replacement to cement, sand or both. Now in our case, cement has been replaced partially with in varying proportions likewise from 0% to 20% and its effect has been analysed onthe standard consistency, soundness, setting times of cement and compressive strength of cement mortar mixes. The cubes and cylinders of concrete were casted for variable content of dolomite powder.
