Abstract

This study explores the influence of various admixture combinations on the performance of Self-Compacting Concrete (SCC), with an emphasis on its flow behavior, compressive strength, tensile strength, flexural strength, and resistance to impact. Various admixtures, including Air-Entraining Agent (AEA), Water-Reducing Plasticizer (WPC), Retarder (RET), and Accelerator (ACC), were incorporated into the SCC reference mix (SP + VMA) to evaluate their impact on SCC performance. A series of tests—such as slump flow, Orimet, V-funnel, L-box, and U-box tests—were conducted to assess flow characteristics. Strength properties were examined through compressive, tensile, flexural, and impact strength tests. The results indicate that SCC with AEA, WPC, and RET generally exhibited improved flow characteristics compared to the reference mix, attributed to the ball-bearing effect of air bubbles and reduced friction among particles. The addition of ACC decreased flowability but accelerated strength gain. Strength tests showed modest increases in compressive, tensile, and flexural strengths with AEA, WPC, and ACC, while RET led to a slight reduction in strength. These findings highlight the potential of tailored admixture combinations to optimize SCC properties, suggesting that AEA and WPC enhance both flowability and strength, while ACC accelerates setting for early-strength applications

Keywords: Self-Compacting Concrete (SCC), admixtures, flow characteristics, compressive strength, tensile strength, flexural strength, impact strength, air-entraining agent, water-reducing plasticizer, retarder, accelerator
