This research studied on the utilization of industrial wastes as pozzolanic material to replace Portland cement type I at replacement rates of 40 and 50 % by weight of binder. Industrial wastes were including fly ash and ground granulated blast furnace slag. Concretes were produced and tested for mechanical and durability properties. Objective was to utilize the industrial wastes and reduce the waste disposal. Results showed that industrial wastes including fly ash and ground granulated blast furnace slag had the potential to replace the cement. However, the strength property of pozzolan concretes were lower than Portland cement concrete at early age, However the strength tended to be increased at later age due to pozzolanic reaction. Carbonation of pozzolan concrete was rapidly penetration. Moreover, pozzolan concrete was resistant to chloride penetration better than Portland cement concrete. In addition, it had low expansion in sulfate solution because of low cement content and pozzolanic reaction in pozzolan concrete made from fly ash and granulated blast furnace slag.
