Abstract- Reactive Powder Concrete (RPC) is a developing composite material that will allow the concrete industry to optimize the material use, generate benefits by build structures that are strong, durable and sensitive to environment. This study is intended to explore the suitability of providing the reactive powder layer as cover to the normal column (M30). In this study Modified RPC is given in two different layer thickness (2.5cm thick and 5cm thick) and finding the compressive strength and durability of the newly composite structure. Modified Reactive Powder Concrete (MRPC) refers to the mix which is free from quartz sand and steel fibers, which are normally present in RPC; and MRPC column is the column having an inner core filled with normal concrete (M30) and outer portion with MRPC mix. MRPC mix is provided in two different thicknesses for checking its effectiveness and durability of each type of column. Specimen of 650 mm height and 200 mm diameter is casted for compressive strength test and 150 mm height and 200 mm diameter is casted for durability test. Seven day and 28 day compressive strength of the newly modified column shows more compressive strength than the normal concrete column and the 5cm thick layer shows more strength. So we can provide the MRPC as cover to the normal column.
