Abstract
In order to improve the durability of hydraulic concrete,in this paper,the effects of copper tailing powder on the mechanical properties,impermeability,antifreeze properties and chloride ion penetration resistance of hydraulic concrete were studied.The results show that the early compressive strength of concrete can be improved when the content of copper tailing powder is less than 10%,but the 28d compressive strength gradually decreases with the increase of copper tailing powder content.The impermeability and chloride ion penetration resistance of concrete decrease first and then increase with the increase of copper tailing powder content.When the copper tailing powder content is 10%,the impermeability and chloride ion penetration resistance of concrete are the best.With the increase of copper tailing powder content,the quality loss rate of concrete after different freeze-thaw cycles decreases first and then increases.关键词
