THE USAGE AND STUDY OF MARINE ENGINEERING HIGH PERFORMANCE CONCRETE WITH GROUND GRANULATED BLAST FURNACE SLAG POWDER

摘要

Along with development of mill technology,ground granulated blast furnace slagpowder (GGBFSP) was extensively used in making up high performance concrete. In thispaper,marine engineering high performance concrete (MEHPC) with GGBFSP was studied.Electric quantity and chloride penetration coefficient were emphatically studied. Theresistance to chloride properties of reference concrete decreases with decreasing of water tocement ratio,but reference concrete doesn't satisfy the durability of MEHPC. The electricquantity and chloride penetration coefficient of high performance concrete whose water-binder is 0.35 remarkably decrease by replacing some cement with GGBFSP and it satisfy theproperties of resistance to chloride. The suitable content of GGBFSP is 70% or so. MEHPCwith GGBFSP was used in Yangshan Port of Shanghai International Shipping Centre.
