Determining the Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) of Roller-Compacted Concrete: A Basis of Its Optimum Design Mix

Year: 2024

Type: conference-paper

Abstract: Roller-Compacted Concrete (RCC) emerges as a viable solution, offering durability and cost-efficiency while minimizing environmental impact.This study evaluates RCC's performance in the Philippines, focusing on two mixes-M1 and M2designed with different aggregate compositions and cementitious materials.The study also examines the physical and chemical properties of materials like Class F fly ash (for M2) and Type I Portland cement (for both M1 and M2), essential components enhancing RCC's sustainability and performance.M2, characterized by a higher Maximum Dry Density (MDD) of 2,309 kg/m³ and lower Optimum Moisture Content (OMC) of 6.4%, demonstrates superior compactibility and potential strength compared to M1. Findings highlight M2 as the optimal mix for RCC slabs, emphasizing its potential for reducing construction time and costs while meeting long-term durability requirements.Recommendations include promoting RCC adoption, optimizing material selection, and investing in research to further enhance sustainability and performance in the pavement industry.
