Abstract:
The current study explores the optimization of roller compacted concrete (RCC) aiming at achieving zero-slump concrete. The RCC, composed of cementitious materials, sand, dense graded aggregates, and water, is primarily employed for pavements and various industrial applications. In this study, different RCC formulations were developed by replacing ordinary Portland cement (OPC) with ground granulated blast furnace slag (GGBS) at varying percentages (0%, 20%, 40%, and 50%). The investigation involved determining the optimal water content for each mix through comprehensive compaction tests at different replacement levels. The focus was on analysing the enhancement in the strength properties of RCC mixes with GGBS. The results indicate that RCC compositions incorporating GGBS exhibit lower early-age strength as compared to conventional OPC concrete. However, the strength of GGBS-modified mixes exhibits improvement over time, ultimately surpassing the compressive strength of normal OPC concrete. Notably, the test outcomes indicate that the strength properties of RCC mixes blended with GGBS increase significantly up to a 40% replacement level of OPC with GGBS.
