ABSTRACT
The concrete specimens were fabricated in the structure and concrete Laboratory at the building and housing research center (BHRC). Experiments included 25 cylindrical and 15 prismatic concrete specimens. The column models were made of a relatively high-strength concrete with no air-entrainment. The concrete reached an average uniaxial compressive strength of about 50 MPa. The specimens were removed from the forms after 2 days and put into water to be moist cured. The cylindrical and prismatic specimens were tested after 428 days after casting.
