Cement is a very valuable commodity as it can be used to construct structurally sound buildings and infrastructure. However, in many developing countries cement is expensive due to the unavailability of local resources and to produce enough cement to meet the demand it must be imported. During manufacturing of 1 tonne of OPC, an equal amount of carbon-di-oxide are released into the atmosphere. Use of cement and aggregates may lead to active shortage in the future. Disposal and pollution problems can be reduced to greater extent by partially replacing the cement using GGBS and copper slag obtained from industries. This study investigates the use of GGBS as partial replacement of cement and copper slag as partial replacement of fine aggregate (each with a proportion of 30%, 50%, and 70%). To evaluate these replacements on the properties of the OPC mix, a number of laboratory tests were carried out. The destructive tests to be carried out (7, 14 and 28days) in this project are compressive strength (cube size:150mmx150mm), flexural strength (beam size 500mmx100mmx100mm), split tensile strength of concrete (100mm diameter and 200mm height cylinder) and the non-destructive tests such as Ultrasonic Pulse Velocity and durability tests such as Rapid Chloride Penetration test. Finally, the test results are compared with conventional concrete and the percentage savings in cost has been worked out.
