Abstract : Concrete in mostly widely used construction material around the world today. Concrete uses cement as binder for other inert ingredient. Cement is an energy intensive materials, produced using non-renewable natural resources like lime stone, clay, shale etc. In the process of manufacture, large amount of carbon dioxide is emitted leading to damage to environment. In fact, cement, which accounts for about 6-7% of total CO2 emission around the world is single largest polluter today. Efforts are underway to reduce this emission and one of the most commonly used method is to reduce clinker content in concrete, by using supplementary cementitious materials, fillers and other byproducts. Portland Limestone Cement is one such attempt, reducing CO2 emission to a significant level. The cement is already in use in Europe and North America and attempts are being made in Asian countries to use the same. The paper reports performance of an experimental Reinforced Concrete structures, about 5 years old constructed with Portland Limestone Cement concrete.
