Effect of the Entrained Air Void on Strength and Interfacial Transition Zone of Air-Entrained Mortar高辉1,2,ZHANG Xiong1,ZHANG Yongjuan11. Key Laboratory of Advanced Civil Engineering Materials... voids on the paste-aggregate interfacial transition zone(ITZ) was analyzed by microhardness. The results show that the correlation between different pore size range and the compressive strength......
is similar to that of the traditional solid-state diffusion layer, and the relationship between the width of liquid zone and holding time obeys a square root law. Key words: Ti; Cu; contact reaction... is less. And the EPMA results show that the width of eutectic reaction liquid zone is much wider than the width of the solid-state diffusion zone of Ti and Cu base metals (the white zone between Ti......
Corrosion Behavior of a Low-Carbon Steel in Simulated Marine Splash ZoneHuan-Huan Wang,Min DuKey Laboratory of Marine Chemistry Theory and Technology, Ministry of Education, College of Chemistry and Chemical Engineering, Ocean University of China摘 要:Experiments were designed to simulate the corrosion of a low-carbon steel exposed to a marine splash zone......
Investigation of the Interfacial Transition Zone between Aggregate-Cement Paste by AC Impedance Spectroscopy孔丽娟,HOU Lirong,WANG Yuhua,SUN GuowenSchool of Materials Science and Engineering... of connected pores RCCP was used to characterize the microstructure of the interfacial transition zone(ITZ).The results show that the RCCP of concrete sample with aggregate is lower than that of cement paste......
