DETECTING THE PROPAGATION OF THE KIDNEY-SHAPED FATIGUE FLAWS IN RAIL HEADS ON THE LINES OF THE HUNGARIAN STATE RAILWAYS

We partially submerged 710 reinforced concrete blocks in a saturated sodium chloride solution. Based on the test no intention for it to be extended in the near future. The concrete causes the steel to change from a passive to an length includes 156 one-track tunnels (54-404 miles) and showed that increasing the cement factor and increasing the length of water curing increased the time to an active half-cell potential. Steam curing of the concrete resulted in a reduction of the time to an active half-cell potential as well as a reduction in absorption as compared to just water curing. The test procedure used verified capillary action as the primary mechanism of water absorption. The chloride content of the concrete was determined. Of the three tested admixtures and corrosion inhibitors, only
