Abstract
Introduction:
It is very important to accurately predict the shrinkage of reinforced concrete specimens to ensure structural safety.
Methods:
In this study, a total of 36 reinforced concrete specimens were used with a size of 150mm×150mm×450mm to examine concrete strength grades and longitudinal reinforcement ratios on the shrinkage of reinforced concrete specimens using shrinkage tests.
Results:
The results showed that the concrete strength increased from 35MPa to 58.2MPa, and the shrinkage rate of concrete decreased by about 30%. The ratio of reinforcement increased from 0 to 2.01%, and the shrinkage rate of concrete decreased by about 40%.
Conclusion:
The experimental results were compared with existing shrinkage models of reinforced concrete, and a modified shrinkage calculation model of reinforced concrete was proposed.
