Gradations. An optimized gradation based on aggregate availability and project requirements will result in an economical concrete with good workability and finishability. The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired.Optimized Aggregate Gradation for Structural Concreteof coarse aggregates (quartzite, limestone and granite) were selected for blending and optimization with medium sand (FM = 2.84) in different proportions to satisfy the target gradation. After optimizing the aggregate gradation the cement content in the concrete mixAggregates: A Vital Component of Your Mix Design - NPCAJan 13, 2017· This does not mean that the precaster should ignore gradations. Instead, this permits the precaster to optimize mix designs by selecting aggregate gradations and blends outside of those included in the standard. Consider closely examining your gradations and optimizing to improve economy and performance.Methods of Predicting Aggregate Voids - KDOT: HomeSimplified methods of predicting aggregate voids were studied to determine the feasibility of a range of gradations using aggregates available in Kansas.
