The particle size of the raw materials is important for many reasons. The particle size distribution has various effects on the processing of building materials, for example:Different Types & Sizes of Aggregate for Concrete » .11/8/2018· It comes in different gradations: sharp sand, builder's sand, and kiln-dried silver sand, which vary from coarsest to finest, respectively. Finer sands are a good aggregate for mortars and grouts. Coarser sands are also a popular aggregate for concrete mixes.Effect of Particle Shape of Limestone Manufactured .Abstract The particle shape parameters of natural sand and limestone manufactured sand were studied by the DIP method. The results showed that compared with the natural sand, the manufactured sand was more 19.0% in lengthwise ratio, less 11.5% in flatness ratio, more 0.3% in convexity ratio, more 0.2% in fulness ratio, less 19.3% in particle shape parameters, and less 14.8% in sphericity. ...

Coarser sands are also a popular aggregate for concrete mixes.Chapter 5: Aggregates For ConcreteIdeal particle is one close to spherical in shape (well rounded and compact) with a relatively smooth surfaces (natural sands and gravels come close to this ideal). More angular shapes - rough surfaces – interfere with the movement of adjacent particles (less workable) –They also have a higher surface –to –volume ratio – more paste.Characterization of Manufactured Sand Particle Shape, .Science DirectImportance of the Particle Shape on Mechanical Properties of Soil .particle shape influence technical properties of soil material and unbound aggregates (Santamarina and Cho, 2004; Mora and Kwan, 2000). Among documented properties affected by the particle shape are e.g. void ratio (porosity), internal friction angle, and

In HMA, since aggregates are relied upon to provide stiffness and strength by interlocking with one another, cubic angular-shaped particles with a rough surface texture are best.
