DEVELOPMENT OF SELF-COMPACTING CONCRETE MIX DESIGN: IMPLEMENTING BAILEY AGGREGATE GRADATION TECHNIQUESAbstract
To achieve the desired fluidity, resistance to segregation and sufficient strength in self-compacting concrete (SCC), it is crucial to choose and optimize the aggregate gradation. The Bailey aggregate gradation process, initially designed for hot mix asphalt, provides a systematic way to mixing aggregates for use in concrete mix designs. Bailey gradation was compared to more traditional methods in a series of experimental studies using varying aggregate quantities. Slump flow, compressive strength, segregation resistance, and L-box passage ratio were the key features that were examined. The results demonstrate that by controlling the particle distribution more precisely, the work ability and mechanical qualities of the SCC are improved when Bailey aggregate gradation is used. This method improves SCC\'s overall efficiency by refining the mix design, making it more suited for use in complicated and packed form work environments. Work ability, void content, and balanced particle packing density are all enhanced when SCC mix designs are optimized using the Bailey approach. With the use of the Bailey approach, this research aims to determine the optimal ratio of coarse to fine aggregates so that SCC may achieve its desired properties, such as good flow-ability, passing ability, and segregation resistance, all without sacrificing compressive strength.
