FOURIER TRANSFORMED –INFRARED SPECTROSCOPY (FTIR) STUDIES ON THE CONCRETE/CEMENT MORTAR MASS MADE OF CENT PERCENTAGE RECYCLED COARSE AND FINE AGGREGATES

The entire construction industry has come to a stage where the use of conventional aggregates in the production of concrete has become a rarity due to the depletion of these precious natural resources and the entire construction is left with two alternative one is to find a suitable replacement of conventional aggregates and the other is to stop its usage. since without its usage, life survival is difficult. Hence the world is left with the usage of the first alternative i.e. to find an alternative to conventional aggregate. A step in this direction the research pertains to the usage of the cent percentage recycled demolished coarse and fine concrete aggregates as a suitable replacement material for its usage in the construction industry. The surface Modification and surface treatment methods found to be an effective way of improving the properties of the recycled aggregates and its usage in concrete/mortar has yielded improved mechanical and durable properties. The Fourier transformed –infrared spectroscopy (FTIR) studies were done to find the functional groups in the concrete/mortar mass and its significant impact on the properties and its internal behavior. The FTIR studies done on the aggregate and the concrete/cement mortar mass helped in understanding the formation of the internal mass, the contribution of internal atoms, identification of functional groups and their bond strength, and also the polarity of the bond and its impact on the mechanical properties.
