Durability of Concrete Roads with Blended Cements

The study was conducted to bring out the salient features of blended cements, which go a long way in establishing the durability of rigid pavements. Blended cements not only enhance the life cycle of concrete road by protecting it from chloride and sulfate attack but also reduce the thermal cracking, plastic and drying shrinkage to a large extent which are common with the OPC concrete roads. The views and researches done in this regard highlighting the beneficial aspects of blended cements are brought forward. The paper is aimed at promoting the use of blended cements in rigid pavements not only with a view of economic or environmental issue but also with the high technical values associated with it.
