The upturn in prices of materials for building construction is causing a lot of concern due to more utilization of building materials such as fine aggregate, coarse aggregate for the construction of structures, creating need for research into original materials as alternatives in building and rural infrastructures. Research efforts are directed towards enhancing the use of locally and readily available material such as lateritic soils for the construction. This study presents, the results of an experimental program to study the strength and durability performance of laterized concrete. A total of 108 cubes of 150mm, 108 cylinders 150mm dia X 300mm height and 81 prisms of 100 X100 X 500 mm dimensions were casted and cured in water as well as chemical solution for 7, 28, 60, and 90 days. Laterized concrete is concrete in which some or all of the fine aggregate is from laterite. To perform this investigation, M30 grade concrete is used, mix proportions 1: 1.274: 3.126 (Cement: sand/laterite: granite) with water/cement ratio of 0.45 was used. In this investigation, percentage laterite content (0%, 10%, 20%, 30%, 40% and 50%) exposure periods of 7, 28, 60, and 90 days on the compressive, flexure and splitting tensile strength tests of laterized concrete were investigated and also the effect of varying percentages of sulphuric acid (H2SO4) concentrations 1%, 3% and 5%, exposure periods of 7, 28, 60, and 90 days on the compressive, flexure and splitting tensile strength tests of laterized concrete were investigated. Data results revealed that the laterite fines used could satisfactorily replace the sand up to 30%. By fixing the laterite content as 30% of fine aggregate, the specimens are tested for durability studies under chemical attack. The specimens are immersed in H2SO4 solution for concentrations of 1%, 3%, 5% for an exposure period of 7, 28, 60 & 90 days, and the strengths of concrete at these ages were investigated.
