Importance of Aggregate Gradation of concrete slab
2019-10-25 October 25, 2019. 0. 15936. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines the concrete’s thermal and elastic properties and dimensional stability.

2016-1-6 Most ready-mix concrete producers use their own methods, hire a testing lab, or rely on a vendor. These methods often include a concept of “ideal gradation.” From Fuller’s maximum density curve, the .45 power curve, 8-18, gap grading to the latest “tarantula,” the aggregate gradation has a major impact on performance.

2018-5-18 Aggregates are an important component of concrete. Not only does it give volume to concrete, it also help reduce shrinkage and cost of concrete. In terms of volume, aggregates may take up almost 80% of the volume of concrete. Thus its impact on various properties of concrete cannot be underestimated. And gradation of aggregates is one important contributor.
