Abstract :
As regards if curing stops for some time and then resumes again, then strength gain will also stop and reactive, in this study with choose
suitable curing conditions after improper first curing (recurring) for normal and silica-fume concrete, Effect of this curing conditions on
strength and permeability was investigated. The results from tests such as compressive strength, capillary water absorption and water
penetration under pressure, indicates that curing after 28 days for concretes with improper first curing, especially for silica-fume concretes
could be effective and reduction permeability and increase compressive strength of concretes was observed
