The Experimental Study on Realkalization Repair for the Durability of RC Structure after Fire

Abstract:

Article Preview

The damages to reinforced concrete structures subjected high temperature of fire mainly include the followings: high temperature make the microstructure of concrete be loose and porous, the strength of concrete and steel reduce greatly.The alkaline hydration products of cement was decomposed under the high temperature, which would destroy the alkaline environment of concrete around steel and cause the steel corrosion. In this paper, the machanism of realkalization technique is present. Moreover, method of mercury intrusion pore measurement, SEM analysis and investigation on pH Value of concrete pore solutions experiment were carried out to study the durability repairing efficiency of realkalization technique.
