In this paper, two sets of comparative fatigue tests on weathering steel-concrete composite girders were carried out in the context girder bridges. The load-deflection relationship under loading different environments was investigated contrastively. experimental results show that coupled effect corrosive environment and load, steel still shows obvious corrosion; simple load has no significant s...

Calcium phosphate was encapsulated into mesoporous silica nanoparticles (MSN). The effect of pH on the structure and morphology MSN release calcium from investigated. Epoxy coatings with (3 wt%) non-encapsulated wt% 5 were formulated their anti-corrosive performance evaluated by open circuit potential (OCP) electrochemical impedance spectroscopy (EIS) techniques. Results showed that encapsulati...
