Mechanical Properties and Flowability of High Strength Concrete Incorporating Ground Granulated Blast-furnace Slag姚武摘 要:The high strength concrete (HSC) was produced by partially replacing the normal portland cement with special ground granulated blast-furnace slag ( GGBS) ranging up to 60% . The effects of the GGBS on the flowabilityand mechanical......
recovery The high concentration of sulphuric acid in leachate would increase the addition of antalkali and ammonia, so it is very necessary to reprocess this solution before extracting vanadium. Many... (P204) employed in this study can coextract vanadium and trivalence iron ion, it would lead to a low service efficiency of extractant and a product with high impurity content. Hence, it is necessary......
EFFECT OF CARBON CONTENT ON MICROSTRUCTURE AND PROPERTIES OF HIGH STRENGTH AND HIGH ELONGATION STEELS D.X.Lou1,S.K.Pu1,B.F.Xu2,X.Chen1,A.M.Guo1,Z.X.Yuan2,Y.Chen2,S.B.Zhou1,P.H.Li1 (1.Technical...-rolled high strengthand high elongation steels with retained austenite were studied by discussing the in-fluence of different carbon content. The research results indicate that carbon contenthas......
. Vanadium or V-based solid solution alloys with BCC structure are very attractive because of their high hydrogen absorption and desorption capacity at moderate pressure and temperature[1, 2]. Another reason is that the diffusion rate of hydrogen in vanadium is extremely high. The hydrogenation properties of vanadium have been controlled and improved by alloying with other metals[3-6]. The maximum......
