• Abstract:

  This paper describes the results of experimental research on strength development and freezing-and-thawing resistance of high-strength lightweight concrete incorporating silica fume. The variables for the experiment were type and moisture content of lightweight aggregate and dosage of silica fume. Test results showed the compressive strength of the lightweight concrete substantially increased with using silica fume regardless of type and moisture content of the lightweight aggregate. And the freezing-and-thawing resistance of the lightweight concrete was mainly influenced by the moisture content of lightweight aggregate. From these results, it was concluded that high-strength durable lightweight concrete satisfying the requirement for concrete structures to be used in severe condition such as the arctic region could be obtained by using low moisture lightweight aggregate together with silica fume.
