Crushed stone is a versatile material made from natural rock deposits that are broken down into smaller pieces using a crusher (find out what a crusher is here). It is graded based on size, with specific numbers indicating the screen size used to sift it. These stones vary in size and are categorized into grades to indicate their size and use.

Uniformly Graded Aggregate. In a uniformly graded aggregate, the particles are nearly all the same size. This type of aggregate creates more voids in the concrete, which requires more cement paste to fill the gaps. As a result, uniformly graded aggregates are less dense than well-graded aggregates. Advantages: Easier to mix and handle.

The gradation curve, combined with the calculated percentages, allows engineers to determine if the aggregate is well-graded, gap-graded, or poorly graded. The goal is typically to achieve a well-graded mix, which provides better stability and strength for construction projects.

In other words, sizes differing only slightly cannot be used side by side, and this has led to advocacy of gap-graded aggregate, as distinct from continuously graded conventional aggregate.

GAP GRADED AGGREGATE Gap-graded aggregate contains only a small percentage of aggregate particles in the mid-size range. The curve is flat in the mid-size range. Some PCC mix designs use gap graded aggregate to provide a more economical mix since less sand can be used for a given workability.

3) Uniform-Graded Aggregates. Uniform-graded aggregates consist of particles that are similar or roughly the same size. During sieve analysis, the ideal uniform-graded aggregate has particles that occupy the entire sieving range without any particles being too large or too small. This type of aggregate gradation is created by carefully choosing ...

Hence, there is a need for the development of a simple and systematic model to predict aggregate packing density. The Aggregate Image Measurement System (AIMS) was used to obtain the shape parameters of aggregates. Aggregate shape indices were developed to correlate binary (gap-graded) aggregates.

Given that gap-graded soil lacks certain grain classes, research indicates it has heightened susceptibility to internal erosion [28]. Such soil may arise from construction defects or substandard soil mixing procedures that create voids when using certain grain sizes. Consequently, gap-graded soil was selected for our erosion experiments.

Gap-graded mixes are often specified for exposed aggregate architectural concrete finishes in order to increase the likelihood of obtaining uniform surface appearance. Gap-graded concretes also show less segregation, tend to be more workable at given slumps, permit lower water-cement ratios and develop required strength with lower cement factors.
