Abstract: The attention of most researchers is shifting towards the optimization of building materials by using local contents; the use of indigenous materials; and local industrial by-products unique and abundant in certain localities.Concrete were made with laterite soil taken from different sources replacing the conventional fine aggregate (local river sand) in steps of 5% up to 20%.Their compressive strengths and split tensile strength determined to check for conformity with concrete as with a view of small scale to determine the acceptable percentage 0%, 5%,10%,15%, & 20% replacement.Laterized concrete structures have potentially sufficient strength compared with that of normal concrete.Soil tests were performed on the laterite soil samples to characterize the soils.Classification of the lateritic soil samples within Mailam, revealed that the lateritic soils are mostly sandy clay of high plasticity and may replace sand by up to 20%, though an approximate linear decrease in strength with increasing sand replacement with lateritic soil was observed.In the compressive strength test, cube -30 numbers of 150 mmx150 mm, split tensile strength test cylinder -30 numbers laterite concrete sizes were produced and crushed with the under compressive machine to determine their twenty-eight day compressive strength of specimens.The process of selecting suitable ingredients of concrete and determining their relative amounts with an objective of producing a concrete of required strength as economically as possible is termed as concrete mix design.The Mix Design for concrete M25 grade is being done as per the Indian Standard Code IS: 10262-2009.
