Demystifying the Conversion: 1 Cubic Meter of G5 Crusher to Tons

A common question in construction and bulk material handling is: How many tons are in 1 mètre cube (m³) of G5 crusher? While a direct, single-number answer might seem convenient, the reality requires understanding a key concept: densité.

The Crucial Factor: Densité apparente

The weight (masse) of any material packed into a given volume depends entirely on its bulk density. This density represents how much material fits into a space, including the voids (air pockets) between the particles.

Higher Density: More tightly packed particles = heavier per cubic meter.
Lower Density: Looser packing with more air gaps = lighter per cubic meter.

G5 Crusher Defined

G5 crusher is a specific grading of crushed stone aggregate, commonly used as a sub-base material for roads, pavements, fondations, and other construction projects. It typically consists of crushed rock particles ranging from dust up to about 37mm (or sometimes specified as passing a 37.5mm sieve). Le "G5" designation originates from South African standards (SANS 1083), but similar specifications exist worldwide under different names (like Base Course or Type 2 Sous-base).

The Standard Conversion Range

For G5 crusher, the typical bulk density falls within this range:

Environ 1.4 à 1.6 tonnes par mètre cube.

Donc:
`Weight (tonnes) = Volume (m³) x Bulk Density (tonnes/m³)`

Calculating for 1 Cubic Meter:

Using the average density within that range:
`Weight = 1 m³ x ~1.5 tonnes/m³ = ~1.5 tonnes`

Considérations importantes - Why It's Not Exact:

1. Matériel source: The type of rock crushed (granit, calcaire, quartzite etc.) inherently has different densities.
2. Teneur en humidité: Wet material weighs significantly more than dry material due to water filling voids and coating particles.
3. Compactage & Manutention: How the material is placed and compacted affects its density:

Loose-tipped stockpile: Lower density (~closer to 1.4 t/m³).
Thoroughly compacted in place: Higher density (~closer to or exceeding 1.6 t/m³).
