文摘
- •
The stress-strain behavior of freshly compressed concrete is investigated.
- •
Empirical formulas for the stress-strain curve of the compressed and uncompressed concrete are developed.
- •
Compressing the fresh concrete increases the amount of energy absorption.
- •
Compressing the fresh concrete increases the linear stage of the stress-strain curve.
