THERMAL DETERIORATION OF WEAR COAT: A PAVING PATH TO CORROSION OF CONCRETE STRUCTURES

R. Selvaraj, M. Amirthavarshini, Dr. S. Prabavathy

Abstract :

Concrete structures such as idges, runways and harbour decks etc., have been subjected to heavy vehicular traffic and the area exposed to such traffic are finished with a wear coat. As these concrete wear coats are open to atmosphere, they are subjected to heating during day time and to cooling during night. As a consequence of thermal cycles, thermal stresses are set up within the materials leading to the cracking of wear coat. These cracks reaching the interface of wear coat and the base concrete, serve as a paving path to all the aggressive species to accumulate and concentrate in it and at the interface, thus supplying the same to the base concrete and thereby initiating the corrosion. In this paper an attempt has been made to quantify the thermal stresses developed due to thermal stresses developed due to thermal swing and suitable remedial measures to overcome this this serious problem have been suggested.
