This paper presents a study conducted to determine the suitability of partial replacement of sand with laterite soil and manufactured sand in M20 grade concrete. The first phase is to find the maximum percentage of sand can replace with lateritic soil and manufactured sand for both M20 grade concrete. Concrete mixes containing 0,10,20,30, 40% sand replacement levels were cast, with super plasticizer. Split tensile strength, compressive strength test and flexural strength were conducted in accordance to the existing standard. Results show maximum of 20% replacement levels of sand by laterite attained workable concrete with satisfactory strength beyond that lateritic concrete is not workable And 40% replacement of sand by manufactured sand shows maximum strength. Mix proportion is taken as 1:1.5:3 based on the design result.
