Green Manufacture of Building Bricks by Carbonating Steel Slags

Abstract:

Carbon dioxide emission and industrial waste recycling have become hot spots of the world's scientific research, and the preparation of brick in CO₂mineral carbonation of steel slag increased gradually. However, there still exists some questions, such as low strength, low carbonization efficiency. Combined with these problems and according to the previous experimental basis, this study aims to further improve the carbonation efficiency and mechanical properties of building materials. In this paper, it studied the influence of carbonization pressure in the preparation of steel slag bricks as building materials by CO₂mineral carbonation. The results show that the optimal carbonization pressure is about 0.25MPa. Under the process parameters, the carbonization efficiency and the compressive strength is 16.6% and 65.1MPa respectively.
