The Application of the Steel Slag in the Radiation Shield Heavy Concrete

Abstract:

The steel slag was broken into steel slag powders and sands. The performance of the radiation shield heavy concrete was studied in this work by mixing different content of steel slag sand and powder. The results showed that the water requirement of normal consistency and setting time increased with the increase of the content of the steel slag powder. The strength reduced in the early stage of the experiment. The strength increased firstly and decreased later. The optimal content of steel slag powder for strength was 20%. For the steel slag powder and sand, whether the concrete added one or two components, the concrete slump loss increased and strength reduced at 3 days. The steel slag powder and sand added into concrete improved the performance of the concrete effectively, solved the heavy aggregate subsidence and improved the concrete homogenous.
