| Abstract | ||||
| This paper presents experimental and analytical investigations on the axial capacity of 12 column using hybrid steel and different types of water. The use of hybrid steel for reinforcing has been confirmed in recent years for stamping out corrosion in steel. One of the main objectives of this study is to examine the effects of using hybrid steel on the compressive strength of R.C columns after mixing with variable water (fresh water, sea water, and 50% freshwater +50% Seawater). 12 reinforced concrete columns use in the experimental program. 9 columns with different weight percentages of steel fiber (16%, 33%, and 50%) from the total Required RFT were studied. For the remaining 3 specimens, one column was tested and used as the control column. In order to compare the compressive strength of our experiment, other side we also poured 18 cubic and 12 cylinders (3 specimens of sea water, 3 specimens of pure water, and 3 specimens of "50% seawater + 50% pure water"), which were checked in 7 days and the same number in 28 days. | ||||
