The effect of sulfate as an environmental factor on the concrete deterioration

Sulfate attack is one of the most important problem on concrete durability,in fact,the sulfate environment of concrete existed is different,such as different concentration of SO~(2-)_4,different temperature and dry-wet circulation etc.The present research of the effect of environmental factor of sulfate on the concrete deterioration is systematic elaborated.The existed research outcome is remarked,the problem existed in the research is pointed out,and the prospects of sulfate attacked concrete are proposed.
