Forty columns were tested to compare lightweight and normal weight concrete with respect to instantaneous response to load, time-dependent shortening characteristics under sustained load, and ultimate strength and strain; results showed that reinforced lightweight columns had greater initial shortenings, but less time-dependent shortenings than did comparable normal weight columns; long-time drying shrinkage effects on non-loaded columns were similar for two types of concrete; ultimate strengths were different; lightweight concrete columns had greater strain capacity during tests to destruction.
