Performance studies of premixed blended hydraulic cement to revolutionize concrete production

Popis výsledku v původním jazyce

In recent years, ready-mix concrete plants have increasingly utilized premixed blended hydraulic cement. These formulations incorporate a higher mineral admixture content than traditional ternary concrete mixtures, resulting in improved durability, compactness, and reduced hydration heat during curing. This study examined four concrete proportions with a water–binder ratio of 0.32, focusing on workability, compression strength, and chloride penetration resistance. The research also considered economic effects and carbon emissions. The findings revealed that premixed blended hydraulic cement improved late strength development and reduced chloride permeability. Additionally, the partial replacement of cement with silica fume enhanced early strength and chloride resistance. However, these benefits came with trade-offs, including adverse effects on workability and increased hydration heat. Notably, a 50% cement mixture in premixed blended hydraulic cement emitted 42–49% less CO 2 than conventional formulations, highlighting its potential for reducing environmental impact in concrete production.
