Concrete's durability and strength to sustain imposed loads makes it one of the most widely acceptedbuilding materials. The present trend in concrete technology is to increase both it strength and durability to meet thedemands of the modern construction. The durability can be improved by adding mineral or chemical admixtures or byblending such material with cement. This paper reports and experimental investigation under taken to study thedurability characteristics of ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) concrete with andwithout fly ash. The concrete mix was designed as per IS 10260 : 28 days. Specimens were cast totest strength resistivity,chloride permeability, diffusion and accelerated corrosion.The rapid chloride permeability test (RPCT) value of PPCconcrete was found to be 24% less than that of OPC concrete. Similarly the resistivity respectively. By replacing 10% ofthe cement fly ash in OPC concrete the durability properties was comparable to that of PPC concrete. Inc reasedreplacement levels of 10%, 20% , 30% , 40% and 50% further improved the durability properties.
