STEEL FIBERS MADE FROM STEEL CANS IN CONCRETE ENGINEERING

Recycling steel cans instead of making new products uses so much less energy, pollution, water and water pollution. In Japan in 1994 about 472,000 tons of steel cans could not be recycled. It meant a huge amount of steel plates could be reused as steel fibers to reinforce plain concrete by considering many advantages of fibrous concrete. Reusing of waste steel cans as a construction material in plain concrete can improve concrete properties and also protect corrosion of reinforced concrete. In this matter behaviour of steel fibers made from steel cans in a transparent gel and concrete specimens were studied. Results of experiments showed that such fibers with average thickness of 0.25 mm increase flexural strength of plain concrete about 150%. Durability of these fibers under an accelerated and artificial aggressive environment showed that more than 75% of fibers in the concrete matrix were sound. However, such fibers in contact with steel bars could cathodically protect corrosion of steel bars. (A) For the covering abstract see ITRD E121685.
