The curve is near vertical the mid-size range, and flat and near-zero the small-size range. Uniformly graded. Refers to a gradation that contas most of the particles a very narrow size range. In essence, all the particles are the same size. The curve is steep and only occupies the narrow size range specified.

Fe Aggregate: designation given to the smaller aggregate sizes with D less than or equal to 4 mm. Fes: particle size fraction of an aggregate which passes the 0.063 mm sieve. Gradg: particle sized distribution expressed as the percentage by mass passg a specified set of sieves.

Right from gradg to the shape, texture and ertness of the aggregate material, there are several quality parameters that can fluence the quality and cost of production of a screed. Grade: Gradg is the process of classifyg aggregates to uniform lots based on particle size.

The gradg curve of an aggregate is a fundamental characteristic for mix design that can easily be modified to adjust several mix properties. While sieve analysis remas the reference method to determe this curve, optical devices are developg, allowg easier and faster assessment of aggregate gradg.

Good gradg implies, sample of aggregates contag all standard fractions of aggregate required proportion such that the sample contas mimum voids. Well graded aggregate contag mimum voids will require mimum paste to fill up the voids the aggregate.
