Strength Properties on Concrete by Partial Replacement of Cement with Dolomite and Fine Aggregate with M-Sand

Abstract: This paper deals the fresh and hardening property of concrete made with M-Sand as sand and dolomite powder as cement replacement in different percentages of cement by dolomite powder is 0, 5, 10, 15 and 20% fine aggregate by M-Sand is 0, 10, 20, 30 and 40 by the weight of M40 grade concrete. The test specimens were cured and tested for compressive strength and split tensile strength in 7 and 28 days for concrete. The maximum strength is obtained for 30% replacement of M-Sand and 15% replacement of dolomite powder.
