Aggregate, is a broad word that describes a “granular material used in construction” (granular meaning particles that do not stick together). Typically, aggregate material is extracted from quarry sites using heavy machinery, and crushed to produce varying sizes. This can be filtered out by size to be used in various applications that we

· Abstract. The 4-parameter Compressible Packing Model (CPM) has been developed to predict the packing density of binary mixtures of spherical particles. The four parameters are: the loosening effect parameter a, the wall effect parameter b, the compaction index K and a critical cavity size ratio x0. The two geometrical interactions

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Key points. • ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).
