英语翻译
Time to initiation of corrosion and subsequent corrosion rates of steel
reinforcement in plain and microsilica-blended concretes were determined
on prismatic 100 x 62.5 x 300 mm (4 • 2.5 x 12 in.) specimens containing
a 12.5 mm (1/2 in.) diameter bar embedded centrally.The length of the
uncoated portion of the bar was 275 mm (I1 in.).The coarse aggregate was
a maximum size of 19 mm (3/4 in.) of crushed limestone with a bulk specific
gravity 2.42 and an average absorption of 3.8%.The fine aggregate was
beach sand of specific gravity 2.70 and absorption 0.23%.A water/cement
(w/c) ratio of 0.50,cement content of 357 kg/m 3 (600 lbs/cu yd),and coarse
to fine aggregate ratio of 2.0 by weight was used for the plain and the
microsilica-blended cement concretes.The specimens were cured for 28 days
before exposure to the chloride solution.
