Abstract

Abstract

The annual output of steel slag in China exceeds 100 million tons, with huge accumulated storage and low utilization rate, which has caused serious harm to the ecological environment. Based on this, this paper carried out the application research of steel slag powder in high performance concrete. The results showed that when the content of steel slag powder exceeded 30% of the total amount of binder, the compressive strength of concrete presented a significant reduction trend. The greater the content of steel slag powder in the total amount of glue material, the more significant its impact; with the increase of steel slag powder and glue material, the impermeability of concrete was significantly improved. When the amount of steel slag powder accounted for 40%~50% of the total amount of glue material, the frost resistance of concrete was relatively better. With the increase of steel slag powder content, the hydration heat of steel slag powder concrete decreased significantly. The temperature rise experiment of mass concrete specimen showed that the steel slag powder concrete specimen could significantly reduce the temperature rise in the center of the concrete specimen, and effectively inhibit the temperature rise cracking of mass concrete specimen, compared with the slag powder and fly ash mixed concrete specimen. The results provided a theoretical basis for the application of steel slag powder in concrete.
