    In order to meet the performance requirements of the concrete for various infrastructure projects, concrete mixers have to be designed and produced using combinations of different cementitious materials with water and aggregate and chemical admixtures. The active constituent of concrete is cement paste and largely it determines the performance of the cement paste, also setting time acceleration or retardation can be achieved by the use of admixtures. In addition of some particular admixture may develop undesirable interaction between varying ingredients of concrete. Many times addition of admixture beyond the certain limit may show incompatibility. The constituent materials of making concrete confirm to Indian standard specifications, but different types of cement vary from batch to batch and brand to brand in there chemical composition. Therefore in this study the compatibility of a chosen admixtures (Auromix 200, Master Glenium sky 8341, Master Rheobuild 1126 N D and Master Glenium sky 8233) with different brands of 53 grade ordinary Portland cement ( ACC cement, Birla Super cement, Dalian cement, Ramco cement and Maha cement ) have been determined by optimum dosage and efficiency of admixtures by marsh cone test.
