Aggregate
What Is Aggregate?
Aggregate is the general term for sand and gravel particles that make up approximately 75% of the volume of concrete, obtained by crushing and screening natural rock formations, and that provide the structural skeleton and strength of concrete.

How Is Aggregate Produced?
The production process begins with the collection of samples from quarry sites that have undergone geological surveys. The hardness, density, and
chemical composition of the rock are analyzed in a laboratory environment to test its suitability for concrete production.
Rock formations approved for quality are separated from the main mass using controlled drilling and blasting methods. The resulting run-of-mine (unprocessed)
material is loaded onto trucks and transported to the crushing plant.
The four main stages of aggregate production:
Drilling & Blasting (Raw Material Extraction)
Loading & Transportation
Crushing (Crusher) – Screening / Sizing
Stockpiling
Rock materials extracted from nature are processed through crushing and screening operations to be transformed into aggregates that comply with standards.
Large rock fragments delivered to the facility are reduced to smaller sizes by passing through primary and secondary crushers.
This process preserves the angular structure of the stone, ensuring better bonding with concrete.
The crushed materials are sent to vibrating screening systems, where they are precisely separated by size into Fine Aggregate (Sand),
Coarse Aggregate (Gravel/Crushed Stone), and Stone Dust.
To improve aggregate quality, clay and dust layers on the material are removed in washing units. Samples are taken from each produced batch,
and granulometry (particle size distribution) and flakiness tests are performed.
Aggregates that pass quality approval are stockpiled in separate compartments according to size to prevent cross-contamination and are prepared for dispatch.
As the largest component of concrete, aggregate is of vital importance to the strength, durability, and overall quality of the structure.
