Effect of Curing Conditions on Hydration Performance of Steel Slag
摘要
Abstract
The strength of the cement added with steel slag powder as supplementary cement materials in different curing conditions was studied and compared with that of added with sand powder. The dissolution of active silicon in the action of the alkali solution, the reaction of saturated calcium hydroxide solution and microscopic structure were tested. The effects of different curing conditions on hydration performance of pulverized steel slag was discussed in this paper. The results showed that in curing conditions of normal temperature, the strength of 3 d, 7 d and 28 d of the steel slag is higher than that of sand power, the early hydration activity of the steel slag is higher than sand powder, and the hydration degree reduced with the age of increase. In the curing conditions of 80 ℃ water, the strength of the cement added with steel slag are higher than that of the cement added with sand power in conditions of the equal content. Compared with the normal temperature conditions, the consumption of Ca ( OH ) 2 of the steel slag obviously increase in the curing conditions of 80 ℃ water, the amount of the generation of hydration products is much more, hydration reaction degree is higher than sand powder. Water hot maintenance condition is good for arousing the steel slag activity, improving its hydration reaction degree, increasing the strength of samples.关键词
