Effect of severe environment and radiation on the behavior of cementitious materials modified by CKD and GBFS

Year: 2024

Type: article

Abstract: Although concrete has many advantages as a construction material under normal settings, its behavior under extreme conditions has yet to be fully investigated, particularly with new advances in concrete technology and the need to create sustainable concrete. This study looks at the strength of modified cementitious materials in harsh situations. To test strength during sodium chloride exposure and radiation, 62 specimens were manufactured with various concentrations of Granulated Blast Furnace Slag (GBFS) and Cement Kiln Dust (CKD). The results show that GBFS-modified materials outperformed CKD. Specimens treated with 15% sodium chloride showed a greater loss in strength than those exposed to 5% sodium chloride. Cementitious materials changed with GBFS are more resistant to salts (sodium chloride) than those modified with CKD. Cementitious materials with GBFS demonstrated better gamma-ray shielding properties for CKD in "HVL" and "TVL". Increasing thickness has no significant influence on the Linear Attenuation Coefficient.
