Abstract

Recent advancement are made in the retrofitting techniques to enhance the characteristics like safety, serviceability and restorability of the structure which are susceptible to damage. More recently, there has been an increased research attention towards advanced techniques which emphasizes on the use of reactive powder concrete (RPC) for maintaining the existing as well as the new structure. RPC is an ultra high performance concrete (UHPC) which is a composite material formed by using Portland cement, silica fumes, quartz sand, steel fibre and super plasticizers. RPC as a material can be used at elevated temperatures where it will serve high bond strength and durability with normal concrete than any other retrofitting material. There is no effect of thermal cycling up to certain degrees on Reactive Powder Concrete therefore it can be used in hot weather condition. This paper is an overview of previous studies done in the field of retrofitting of structure using different techniques and highlights the advantages of RPC as a retrofitting material.
