Effects of super plasticizer and curing conditions on properties of concrete with and without fiber

In this study, effects of super plasticizer (SP) and curing conditions on properties of concrete with and without fiber were investigated. In the concrete mixtures, Portland cement, artificial aggregate, SP and steel fibers were used. SP in concrete mixtures was used with ratios of 1.0%, 1.5%, and 2.0% by weight of cement and so C25 concrete was produced with and without fiber. Specimens were cured under two different curing conditions being continuous moist curing and open-air curing. Produced concrete with and without fiber were compared with each other as well as with Portland cement concrete. The highest compressive and flexural strength were obtained with 1.0% and 1.5% SP fiber reinforced concrete, respectively.
