Supply chain
The quality of the material that reaches site is the outcome of decisions at every stage, from choosing the source to loading.
StagesFrom source to site
From source to site
This section explains the general stages of producing and supplying aggregates, and how each one affects the final product.
- Sourcing
01Source identification
The quality of an aggregate is set by the geology of its source before any operation begins. Rock type, deposit uniformity, clay and impurity content and face stability are the main criteria for assessing a source.
- Extraction
02Extraction
Benched extraction from a quarry face or alluvial bed is carried out with planned sequencing and dust control, so that plant feed stays uniform.
- Crushing
03Crushing
Staged crushing in jaw, cone and impact crushers sets particle size and shape. Cubical particles improve concrete workability and interlock in pavement layers.
- Screening
04Screening and grading
Vibrating screens separate material into defined size ranges. Conformity of the grading curve with the reference standard is a precondition for a stable mix design.
- Washing
05Washing
Washing removes clay, silt and organic matter clinging to the particles and brings the percent finer than the 75 µm sieve within limits. This stage directly affects cement paste bond.
- Quality control
06Quality control
Regular sampling and tests such as grading, sand equivalent and Los Angeles abrasion show whether each shipment conforms to the order specification.
- Delivery
07Stockpiling, loading and haulage
Separate stockpiles and controlled loading prevent mixing and segregation. Coordinating haulage with the site schedule keeps the work continuous.
