Performance of Steel Reinforcement in Portland Cement and High-Volumen Fly Ash Concretes Exposed to Chloride Solution

摘要

This paper describes the performance of steel reinforcement in port- land cement and high-volume fly ash (HVFA) concretes exposed to a chloride solution. A number of large slabs, 833 x 600 x 153 mm in size, were cast from six air-entrained concrete mixtures. Four of these mixtures were made with normal portland cement with the water- cement ratio (w/c) of the mixtures ranging from 0.32 to 0.76 ; the remaining two mixtures were made with the HVFA concrete with a w/(c+FA) of 0.32.
