Mechanical Analysis on Reinforced Concrete Beams under Salt Fog Corrosion Test
In the background of buildings in coastal area being corroded by salt fog, this paper studies 12 beams of different intensity and protective layers to simulate the real effect of the corrosion for 20 years. Elaborates the phenomenon of enhancement of the concrete compressive strength and the bearing capacity and cracking load of test beams, and makes an indepth analysis on the mechanism of this phenomenon, at the same time the concept of the additional expansion prestress is introduced; a mathematical model of the additional expansion prestress is establish and the computational model of the cracking load is derived.
