镍铁矿渣代替细骨料应用于混凝土生产的可行性研究

The experimental study on the application of nickel iron slag instead of fine aggregate in concrete production

本文根据镍铁矿渣的特性,通过对镍铁矿渣进行进一步处理,达到符合混凝土的细骨料使用标准,验证细骨料替代量对混凝土强度的影响,同时根据其化学组分设计试验进行安定性验证,确保作为细骨料使用的安定性合格,保证混凝土不因镍铁矿渣的安定性问题使耐久性下降。

According to the characteristics of the nickel iron slag, through the further processing of nickel iron slag, the nickel iron slag achieved the concrete fine aggregate standard. Then we verifide the effect of amount of fine aggregate substitute on concrete strength, at the same time, according to its chemical composition design experiment verified the stability, ensured that used as fine aggregate stability of qualified, and durability of concrete is not declined because of the nickel iron slag stability problem.
