ABSTRACT
Loading system applied was shown in Fig. 2. Accelerated test1), 2) adopted in this paper was the following conditions,
Salt water : 3% of salt (by weight) No. of cycles : 2 cycles/day, Temperature : 60°C (const.) Salt water spray : 3 hrs./cycle, Drying : 40% R.H. Corrosion of bars was measured with the following items, that is, corroded area,
corroded length, depth of corrosion and loss of weight due to corrosion. Corroded parts were removed by way of solution of 2 anmoniun citrate. Chloride content in concrete was measured with the tilting method of silver nitrate3)
