Abstract

Abstract

This is an article in the field of ceramics and composites. In order to study the mechanical properties and durability of iron tailings concrete after being subjected to the dry-wet cycle of sodium sulfate solution, the compressive test, chloride ion corrosion test, frost resistance test and hydration characteristics test of the concrete eroded by sodium sulfate solution are carried out. The effects of different iron tailings content, number of dry and wet cycles, and solution concentration on the mechanical properties and durability of concrete are analyzed. The results show that when the iron tailings content is 30%, the number of dry and wet cycles is 60 times, and the sodium sulfate concentration is 5%, the mass loss rate of concrete is the smallest and the compressive strength and corrosion resistance coefficient is the largest. As the content of iron tailings continues to increase, the better the corrosion resistance and frost resistance of concrete will be and the heat of hydration reaction decreases.
